Fix accepting INET fd bug.

This was introduced in commit: 9f727c1e267f1363012a3af599b7d7515e4ec355.

While pgpool_main initializes itself, first accepting UNIX/INET domain
sockets are set in "fds" array.  Then forks child process.  So far so
good. Later on pgpool_main initializes pcp sockets. But at this point
it accidentally initialized "fds" array again. As a result, if child
process is forked again, wrong fds were used by those child
process. Immediate result is, frontend could not connect to pgpool by
INET domain listen addresses (-h localhost).

Problem found by Bo peng.
