xfs: fix zone selection in xfs_select_open_zone_mru

xfs_select_open_zone_mru needs to pass XFS_ZONE_ALLOC_OK to
xfs_try_use_zone because we only want to tightly pack into zones of the
same or a compatible temperature instead of any available zone.

This got broken in commit 0301dae ("xfs: refactor hint based zone
allocation"), which failed to update this particular caller when
switching to an enum.  xfs/638 sometimes, but not reliably fails due to
this change.
