Darrick J. Wong 7c2d238ac6 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.
