Check for error from some guestfs_set_* calls (found by Coverity).

Browse Source 
For some guestfs_set_* calls, add checks for error, when error might
possibly occur.  eg. It's plausible that guestfs_set_network might
fail if the attach-method being used doesn't support it (although this
doesn't happen at the moment).

In other cases, don't check for errors, eg. if the error doesn't
matter or there's nothing we could plausibly do about it.
