xfs: remove XFS_PREALLOC_SYNC
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.
