[PATCH] fix up XFS_ERROR() usage in xfs_lrw.c

[Eric Sandeen <sandeen@sandeen.net>]

Fix up a couple of XFS_ERROR callers who send a negative errno
rather than negating the macro itself, at odds with all other
callers (if xfs_etrap contained EINVAL this would not be caught)

(hm, should xfs_read be using generic_segment_checks?)
