Jan Kara b41d730552 udf: Verify inode link counts before performing rename 
[ Upstream commit 6756af923e ]

During rename, we are updating link counts of various inodes either when
rename deletes target or when moving directory across directories.
Verify involved link counts are sane so that we don't trip warnings in
VFS.
