xfs: fixed signedness of error code in xfs_inode_buf_verify

Prior to v3.17, XFS used positive error codes internally.  Commit
af8d971602b9583e5e8400e637e2a48c7480bc64 (xfs: inode recovery
readahead can race with inode buffer creation), upstream commit
b79f4a1c68bb99152d0785ee4ea3ab4396cdacc6 backported from later
releases need the error code signs reversed.  Negative error codes
will cause assertion failures (BUG_ON on kernels with assertions
enabled.
