Subject: [PATCH 05/14] xfs: Remove unused xfs_reflink_compare_extents events

From: Steven Rostedt <rostedt@...dmis.org>

When the clone/dedupe_file_rang common functions were refactored, it
removed the calls to the xfs_reflink_compare_extents and
xfs_reflink_compare_extents_error events. As each event can take up to 5K
in memory for text and meta data regardless if they are used or not, they
should not be created if they are not used. Remove these unused events.

Fixes: 876bec6f9bbf ("vfs: refactor clone/dedupe_file_range common functions")
