xfs: pass a CIL context to xlog_write()

mainline-inclusion
from mainline-v5.14-rc4
commit c45aba40
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=c45aba40cf5b2988c0bebee8c9b846c88aa651eb



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

Pass the CIL context to xlog_write() rather than a pointer to a LSN
variable. Only the CIL checkpoint calls to xlog_write() need to know
about the start LSN of the writes, so rework xlog_write to directly
write the LSNs into the CIL context structure.

This removes the commit_lsn variable from xlog_cil_push_work(), so
now we only have to issue the commit record ordering wakeup from
there.
