totemsrp: Remove recv_flush code

The recv_flush code is no longer necessary because of the miss_count_count
addition.  It can in some cases lead to register corruption because of
interactions with -fstack-protector, the recursive nature of how this code
works, and interactions with the optimizer in some versions of gcc.
