Subject: [PATCH] tools: make --quiet actually suppress output
When calling daemon_stop() with --quiet and e.g. the pidfile is empty,
it won't return early since while "$fail" is set, "$2" is "--quiet", so
the if condition isn't met and it will continue executing, resulting
in error messages in the log:
> Sep 14 14:48:33 localhost watchfrr[2085]: [YFT0P-5Q5YX] Forked background command [pid 2086]: /usr/lib/frr/watchfrr.sh restart all
> Sep 14 14:48:33 localhost frrinit.sh[2075]: /usr/lib/frr/frrcommon.sh: line 216: kill: `': not a pid or valid job spec
> Sep 14 14:48:33 localhost frrinit.sh[2075]: /usr/lib/frr/frrcommon.sh: line 216: kill: `': not a pid or valid job spec
> Sep 14 14:48:33 localhost frrinit.sh[2075]: /usr/lib/frr/frrcommon.sh: line 216: kill: `': not a pid or valid job spec
Fix this by moving the --quiet check into the block to log_failure_msg(),
and also add the check to all other invocations of log_*_msg() to make
--quiet properly suppress output.

```
The issue is that we try to process NLRIs even if the attribute length is 0.
Later bgp_update() will handle route-maps and a crash occurs because all the
attributes are NULL, including aspath, where we dereference.
According to the RFC 4271:
A value of 0 indicates that neither the Network Layer
Reachability Information field nor the Path Attribute field is
present in this UPDATE message.
But with a fuzzed UPDATE message this can be faked. I think it's reasonable
to skip processing NLRIs if both update_len and attribute_len are 0.
