xfs: allow xfs_lock_two_inodes to take different EXCL/SHARED modes
Refactor xfs_lock_two_inodes to take separate locking modes for each
inode. Specifically, this enables us to take a SHARED lock on one inode
and an EXCL lock on the other. The lock class (MMAPLOCK/ILOCK) must be
the same for each inode.
