rpc: rearm listener socket early
Problem:
On node reboot, when glusterd starts volumes, a setup with a large
number of bricks might cause SYN Flooding and connections to be dropped
if the connections are not accepted quickly enough.
Solution:
accept() the connection and rearm the listener socket early to receive
more connection requests as soon as possible.
