ice: remove unused struct member
The only time you can ever have a rq_last_status is if
a firmware event was somehow reporting a status on the receive
queue, which are generally firmware initiated events or
mailbox messages from a VF. Mostly this struct member was unused.
Fix this problem by still printing the value of the field in a debug
print, but don't store the value forever in a struct, potentially
creating opportunities for callers to use the wrong struct member.
