xfs: fix off-by-one error in xfs_rtalloc_query_range
In commit 8ad560d2565e6 ("xfs: strengthen rtalloc query range checks") we strengthened the input parameter checks in the rtbitmap range query function, but introduced an off-by-one error in the process. The call to xfs_rtfind_forw deals with the high key being rextents, but we clamp the high key to rextents - 1. This causes the returned results to stop one block short of the end of the rtdev, which is incorrect. Signed-off-by: Darrick J.
