cifs: don't always drop malformed replies on the floor (try #3)
Slight revision to this patch...use min_t() instead of conditional assignment. Also, remove the FIXME comment and replace it with the explanation that Steve gave earlier. After receiving a packet, we currently check the header. If it's no good, then we toss it out and continue the loop, leaving the caller waiting on that response. In cases where the packet has length inconsistencies, but the MID is valid, this leads to unneeded delays. That's especially problematic now that the client waits indefinitely for responses. Instead, don't immediately discard the packet if checkSMB fails. Try to find a matching mid_q_entry, mark it as having a malformed response and issue the callback.
