Summary:                    [patch] Thread debugging version of
DEADLOCK_AVOIDANCE: wrong line number if re-lock fails.
Description: 
As described in https://issues.asterisk.org/view.php?id=15314, if the mutex
referenced by DEADLOCK_AVOIDANCE goes
away, the "Error obtaining mutex: Invalid argument" error message reports
the line number where the lock was originally obtained, not that of the
failure.

This is because DEADLOCK_AVOIDANCE takes special steps to retain the
original line number.  I believe the intent of this is for accurate tracing
of deadlock origins, but I believe that it should be reporting the actual
line number if the actual re-lock call fails.
