I'm adding Btrfs ioctls to read and write compressed data, and rather
than duplicating the checks in rw_verify_area(), let's just export it.

Could I please get an ack from the VFS side on this patch and "fs:
export variant of generic_write_checks without iov_iter"? We're going
the route of doing this as a Btrfs ioctl since we couldn't agree on a
generic interface, so this is all I need from the VFS.
