BMP: Silence some log messages

Browse Source 
Hooks called from BGP to BMP should not log warning when BMP is not
connected, that is not an error (and we do not want to flood logs with
a ton of messages).

Blocked sk_send() should not log warning, that is expected situation.
Error during sk_send() is handled in error hook anyway.
