Yash Suthar 585abc02be tracing: Replace BUG_ON with lockdep_assert_held in uprobe_buffer functions 
Replace BUG_ON(!mutex_is_locked(&event_mutex)) with
lockdep_assert_held(&event_mutex) in uprobe_buffer_enable() and
uprobe_buffer_disable().

BUG_ON() will crash the kernel. mutex_is_locked() only checks
if any task holds lock,but not the caller task. lockdep_assert_held()
also check current task for lock and no crash on true condition.
