[XFS] kill superflous buffer locking
There is no need to lock any page in xfs_buf.c because we operate on our own address_space and all locking is covered by the buffer semaphore. If we ever switch back to main blockdeive address_space as suggested e.g. for fsblock with a similar scheme the locking will have to be totally revised anyway because the current scheme is neither correct nor coherent with itself.
