[SCSI] qla2xxx: Fix array subscript is above array bounds in qla2xx_build_scsi_type_6_iocbs().

The additional increment of dsd_seg was causing the compiler to throw an array

cmd_pkt->fcp_data_dseg_len so that the compiler doesn't generate an array out

Support is added for quiescence mode. This feature is for P3P
adapters. Any of the functions can put the firmware into quiescence

current commands are processed and all the new incoming I/Os are
blocked. Loop resync is performed after firmware comes out of
quiescence state.

[SCSI] qla2xxx: Handle outstanding mbx cmds on hung f/w scenarios.

Outstanding mailbox commands, have no way to recover on f/w hung, and we
timeout on waiting for mbx response. This in turn affects the recovery process
as follows:
- We might already be in dpc while waiting for mbx to complete, so recovery for
that pci function will never get invoked. Reset Timeout (10 sec) is far less
than mbx timeout (30 sec).
- Other mbx cmds will get stuck due to serial mbx access.

Solution is to identify fw-hung scenario and handle outstanding mbx commands to
have an early-exit instead of waiting for response.
Other mbx commands waiting for access will also do an early-exit if fw-hung is
still applicable.
