ceph: switch to use cap_delay_lock for the unlink delay list

Jay Shin requested to merge jaeshin/centos-stream-9:RHEL-32997 into main

JIRA: https://issues.redhat.com/browse/RHEL-32997

Conflicts: fs/ceph/caps.c, fs/ceph/mds_client.c:

  • Minor conflicts due to missing unrelated upstream commit 38d46409c463 ("ceph: print cluster fsid and client global_id in all debug logs")

commit 17f8dc2db52185460f212052f3a692c1fdc167ba Author: Xiubo Li xiubli@redhat.com Date: Tue Apr 9 08:56:03 2024 +0800

ceph: switch to use cap_delay_lock for the unlink delay list

The same list item will be used in both cap_delay_list and 
cap_unlink_delay_list, so it's buggy to use two different locks
to protect them.
