xfs: log items should have a xlog pointer, not a mount

mainline inclusion
from mainline-v5.17-rc6
commit d86142dd
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I4KIAO
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=d86142dd7c4e10e50bdb3679b405d748214b2c28



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

Log items belong to the log, not the xfs_mount. Convert the mount
pointer in the log item to a xlog pointer in preparation for
upcoming log centric changes to the log items.
