Guangguan Wang f3c46e41b3 net/smc: non blocking recvmsg() return -EAGAIN when no data and signal_pending 
Non blocking sendmsg will return -EAGAIN when any signal pending
and no send space left, while non blocking recvmsg return -EINTR
when signal pending and no data received. This may makes confused.
As TCP returns -EAGAIN in the conditions described above. Align the
behavior of smc with TCP.
