gfs2: Skip dlm unlocks earlier

When we were still caching unreferenced glocks, evicting all the cached inodes
in gfs2_kill_sb() did put the unreferenced glocks onto the glock lru list, and
they would be freed in gfs2_gl_hash_clear().  We could set the
SDF_SKIP_DLM_UNLOCK flag in gfs2_gl_hash_clear() to indicate to gdlm_put_lock()
to skip unlocking glocks explicitly when possible.  Now, glocks are demoted and
dropped immediately though, so to allow gdlm_put_lock() to skip unnecessary
unlocking, we need to set some "unmount" flag before calling
gfs2_evict_inodes().  We can use the existing SDF_KILL flag for that if we set
it before calling gfs2_evict_inodes() in gfs2_kill_sb().
