tracing/probes: Fix to search structure fields correctly

commit 9704669c386f9bbfef2e002e7e690c56b7dcf5de upstream.

Fix to search a field from the structure which has anonymous union
correctly.
Since the reference `type` pointer was updated in the loop, the search
loop suddenly aborted where it hits an anonymous union. Thus it can not
find the field after the anonymous union. This avoids updating the
cursor `type` pointer in the loop.

Merge tag 'probes-v6.6' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace

Pull probes updates from Masami Hiramatsu:

- kprobes: use struct_size() for variable size kretprobe_instance data
structure.

- eprobe: Simplify trace_eprobe list iteration.

- probe events: Data structure field access support on BTF argument.

- Update BTF argument support on the functions in the kernel
loadable modules (only loaded modules are supported).

- Move generic BTF access function (search function prototype and
get function parameters) to a separated file.

- Add a function to search a member of data structure in BTF.

- Support accessing BTF data structure member from probe args by
C-like arrow('->') and dot('.') operators. e.g.
't sched_switch next=next->pid vruntime=next->se.vruntime'

- Support accessing BTF data structure member from $retval. e.g.
'f getname_flags%return +0($retval->name):string'

- Add string type checking if BTF type info is available. This will
reject if user specify ":string" type for non "char pointer"
type.

- Automatically assume the fprobe event as a function return event
if $retval is used.

- selftests/ftrace: Add BTF data field access test cases.

- Documentation: Update fprobe event example with BTF data field.

tracing/probes: Move finding func-proto API and getting func-param API to trace_btf

Move generic function-proto find API and getting function parameter API
to BTF library code from trace_probe.c. This will avoid redundant efforts
on different feature.
