xprtrdma: Add unique trace points for posting Local Invalidate WRs
commit 4b93dab36f28e673725e5e6123ebfccf7697f96a upstream.
When adding frwr_unmap_async way back when, I re-used the existing
trace_xprtrdma_post_send() trace point to record the return code
of ib_post_send.
Unfortunately there are some cases where re-using that trace point
causes a crash. Instead, construct a trace point specific to posting
Local Invalidate WRs that will always be safe to use in that context,
and will act as a trace log eye-catcher for Local Invalidation.
Fixes: 847568942f93 ("xprtrdma: Remove fr_state")
Fixes: d8099feda483 ("xprtrdma: Reduce context switching due ... ")
