scsi: zfcp: the action field of zfcp_erp_action is actually the type

&zfcp_erp_action.action ==> &zfcp_erp_action.type

While at it, make use of the already defined enum for this purpose to get
at least some build checking (even though an enum is type equivalent to an
int in C). v2.6.27 commit 287ac01acf22 ("[SCSI] zfcp: Cleanup code in
zfcp_erp.c") introduced the enum which was cpp defines previously.

To prevent compiler warnings with the switch(act->type), we have to
separate the recently added eyecatchers from enum zfcp_erp_act_type.

Since struct zfcp_erp_action type is embedded into other structures living
in zfcp_def.h, we have to move enum zfcp_erp_act_type from its private
definition in zfcp_erp.c to the zfcp-global zfcp_def.h.

Silence one false -Wswitch compiler warning case: LUNs as the leaves in our
object tree do not have any follow-up success recovery.

scsi: zfcp: drop duplicate seq_no from zfcp_fsf_req which is also in QTCB header

There is no point for double bookkeeping especially just for tracing. The
trace can take it from the QTCB which always exists for non-SRB responses
traced with zfcp_dbf_hba_fsf_res().

As a side effect, this removes an alignment hole and reduces the size of
struct zfcp_fsf_req, and thus of each pending request, by 8 bytes.

Before:
$ pahole -C zfcp_fsf_req drivers/s390/scsi/zfcp.ko

u32 seq_no; /* 152 4 */

scsi: zfcp: drop duplicate fsf_command from zfcp_fsf_req which is also in QTCB header

Status read buffers (SRBs, unsolicited notifications) never use a QTCB
[zfcp_fsf_req_create()]. zfcp_fsf_req_send() already uses this to
distinguish SRBs from other FSF request types. We can re-use this method in
zfcp_fsf_req_complete(). Introduce a helper function to make the check for
req->qtcb less magic.

SRBs always are FSF_QTCB_UNSOLICITED_STATUS, so we can hard-code this for
the two trace functions dealing with SRBs.

All other FSF request types have a QTCB and we can get the fsf_command from
there.

zfcp_dbf_hba_fsf_response() and thus zfcp_dbf_hba_fsf_res() are only called
for non-SRB requests so it's safe to dereference the QTCB
[zfcp_fsf_req_complete() returns early on SRB, else calls
zfcp_fsf_protstatus_eval() which calls zfcp_dbf_hba_fsf_response()]. In
zfcp_scsi_forget_cmnd() we guard the QTCB dereference with a preceding NULL
check and rely on boolean shortcut evaluation.

As a side effect, this causes an alignment hole which we can close in
a later patch after having cleaned up all fields of struct zfcp_fsf_req.
Before:
$ pahole -C zfcp_fsf_req drivers/s390/scsi/zfcp.ko
