Modified Files:
	src/sys/net: if_gre.c

Log Message:
Two bug fixes:

If gre_socreate1() cannot find out the socket's address, exit with
an error.  Before, it could exit *without* an error.

If gre_thread1() finds that it is without a valid socket (i.e., so
== NULL) but the configuration is "unchanged" (in initial state),
force reconfiguration.  This prevents a crash when we try to bring
up a GRE over UDP interface whose UDP endpoints have never been
specified.
