Roland Dreier c5419e6f05 cxgb3: Fix sparse warning and micro-optimize is_pure_response()
The function is_pure_response() does "ntohl(var) & const" and then
essentially just tests whether the result is 0 or not; this can be done
more efficiently by computing "var & htonl(const)" instead and doing the
byte swap at compile time instead of run time.

This change slightly shrinks the compiled code; eg on x86-64 we save a
couple of bswapl instructions:

add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-8 (-8)
function                                     old     new   delta
t3_sge_intr_msix_napi                        544     536      -8

and this also has the pleasant side effect of fixing a sparse warning:

    drivers/net/cxgb3/sge.c:2313:15: warning: restricted degrades to integer
