[LU-629] _debug_req() never prints out opcode/flags/status

• Type: Bug
• Resolution: Fixed
• Priority: Major

Description

The 2.x _debug_req() function was changed in https://bugzilla.lustre.org/show_bug.cgi?id=16359 (commit 5467a860213d454759bdfad91503691d6692b317) to avoid problems with accessing unswabbed message buffers. Unfortunately, this broke the printing of many useful _debug_req() messages, because it didn't check whether swabbing was actually needed in the first place.

Also, in ptlrpc_expire_one_request() some extra debugging information was added in commit 368689640e6a42a152eee73d354dd6f68836065b, but never removed, making this common message overly verbose.
