Gleb Smirnoff 100db364eb Fix two issues with not ready data in sockets (read: sendfile) 
in UNIX sockets.

o Check that socket is still connected in uipc_ready(). If not
  we are responsible to free mbufs.
o In uipc_send() if socket appears to be disconnected, but we
  are sending data with pending I/Os, don't free mbufs.
