Subject: [PATCH 12/14] xfs: Remove usused xfs_end_io_direct events

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

When the use of iomap_dio_rw was added, the calls to the trace events
xfs_end_io_direct_unwritten and xfs_end_io_direct_append were removed but
those trace events were not. As trace events can take up to 5K in memory
for text and meta data regardless if they are used or not, they should not
be created when not used. Remove the unused events.

Fixes: acdda3aae146 ("xfs: use iomap_dio_rw")
