hastd/primary.c micro fixes

[Mikolaj Golub]

Hi,

noticed the following in hastd/primary.c:

1) in init_remote() when incoming connection is set up, if proto_client()
fails it only reports about the error and try proto_connect() anyway. This
will cause a crash as proto_conn structure is not valid. Primary should rather
exit (as it is when outgoing connection is set up, and as it is in the patch
below) or set proto_conn pointer to NULL and goto close.

2) in guard_thread() timeout.tv_sec is set in loop, while it looks like it may
be set only once before the loop.
