net/socket: Fix invalid socket type error handling

Calling error_report() in a function that takes an Error ** argument
is suspicious.  net_socket_fd_init() does that, and then fails without
setting an error.  Wrong.  I didn't analyze how exactly this can
break.  A caller that reports the error on failure would crash.

Broken when commit c37f0bb1d0 (v2.11.0) converted the function to
Error.  Fix by calling error_setg() instead of error_report().
