commit 394d0712d3d46a87a8063e14e998e9c22336e3a6
Author: Anca Agape <anca@fb.com>

Fix rpl.rpl_4threads_deadlock test broken by D5005670
Summary:
In D5005670 in fill_fields_processlist() function we introduced a point
where we were trying to take the LOCK_thd_data before the
synchronization point used by test
processlist_after_LOCK_thd_count_before_LOCK_thd_data. This was
happening in get_attached_srv_session() function called. Replaced this
with get_attached_srv_session_safe() and moved it after lock is aquired.
