xfs: merge _xfs_log_force_lsn and xfs_log_force_lsn

Browse source 
Switch to a single interface for flushing the log to a specific LSN, which
gives consistent trace point coverage and a less confusing interface.

The was only a single user of the previous xfs_log_force_lsn function,
which now also passes a NULL log_flushed argument.
