gfs2: Simplify clean_journal

JIRA: https://issues.redhat.com/browse/RHEL-91331
Upstream Status: https://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2.git

In function clean_journal(), update @Head to point at the log header
that indicates successful recovery:  this is where logging needs to
resume.
