glusterd: Improve debugging experience for glusterd locks
Today, when glusterd's internal locking mechanism fails
with invalid type or when another competing lock is being
held, the log message doesn't provide enough information
directly as to which command saw this (first). Following
is a snippet of how a failure would look in the log file.
This would greatly assist in debugging.
