filelocks: use mount idmapping for setlease permission check
A user should be allowed to take out a lease via an idmapped mount if
the fsuid matches the mapped uid of the inode. generic_setlease() is
checking the unmapped inode uid, causing these operations to be denied.
Fix this by comparing against the mapped inode uid instead of the
unmapped uid.
