mm/xip: share the i_mmap_rwsem
__xip_unmap() will remove the xip sparse page from the cache and take down
pte mapping, without altering the interval tree, thus share the
i_mmap_rwsem when searching for the ptes to unmap.
Additionally, tidy up the function a bit and make variables only local to
the interval tree walk loop.
