[patch] xfs: remove an unneeded NULL check

Smatch complains because we check "commit_lsn" for NULL inconsistently.
fs/xfs/xfs_log_cil.c +705 xfs_log_commit_cil(43) error: we previously
assumed 'commit_lsn' could be null (see line 688)
xfs_log_commit_cil() is only called from one place, and "commit_lsn" is
a valid pointer, so I've removed the NULL check.
