[pgpool-committers: 3406] pgpool: Fixing the error messages when the socket operation fails

[Muhammad Usama]

Fixing the error messages when the socket operation fails

When some socket operation fails, we issue close socket before throwing an
error which causes the errno value to be overwritten and consequently the error
log does not print the correct failure reason.
The solution is to save the errno before closing the socket and use the saved
value to print error description
