posix: Fix the pendinging_recv flag setting.

Browse Source 
The statement in line 1199 is may not be correct:
Actually, it should be following two cases
to pendinging_recv into false;
1  posck->recv_pipe == NULL

2 psock->recv_pipe != NULL  & avalable_bytes == 0;

So this patch can fix this issue.
