Log Message:
Fix return code of __wait_seqno.

MAX(ret, 0) is 0 if ret is negative, but if ret is negative we want
to return that negative value, meaning error.  Should've been
MIN(ret, 0), but I'll just rewrite it to clarify a wee bit.

If the GPU reset, call i915_gem_check_wedge and always return failure
like Linux does.  Caller must retry in that case.
