[PATCH 5.15 02/11] xfs: remove XFS_PREALLOC_SYNC

[Leah Rumancik <leah.rumancik@gmail.com>]

From: Dave Chinner <dchinner@redhat.com>

commit 472c6e46f589c26057596dcba160712a5b3e02c5 upstream.

[partial backport for dependency -
 xfs_ioc_space() still uses XFS_PREALLOC_SYNC]

Callers can acheive the same thing by calling xfs_log_force_inode()
after making their modifications. There is no need for
xfs_update_prealloc_flags() to do this.
