mimic: cephfs: client: unlink dentry for inode with llref=0 #29479
when client get notification from MDS that a file has been deleted(via getting CEPH_CAP_LINK_SHARED cap for inode with nlink = 0), if the client hasnt touch the inode in the past, the ll_ref will be zero. In previous code, we only call Client::unlink when ll_ref > 0, which is wrong and will leave the dn in cache, keeping the caps and resulting the inode stays in stray till the dn cache is dropped by kernel. Under certain workload(write intensive and rotate intensive), this issue can cause stray stacking to 100k+ and causeing huge space "leaking".
