Return -1 instead of calling pfatal in nmap_raw_socket.

Browse Source 
There was one case where we previously didn't fatal, in nse_dnet.cc.
Move the fatal calls out of nmap_raw_socket and into the calling scope,
with the exception of the one in nse_dnet.cc.

The problem was reported by Rob Nicholls.
