xfs: move xlog_commit_record to xfs_log_cil.c

mainline-inclusion
from mainline-v5.14-rc4
commit 2ce82b72
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I4V7IK
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=2ce82b722de980deef809438603b7e95156d3818

-------------------------------------------------

It is only used by the CIL checkpoints, and is the counterpart to
start record formatting and writing that is already local to
xfs_log_cil.c.
