Log Message:
ldpd: remove unused bit-field member from anonymous union

The struct common_hello_tlv contained an anonymous union, which is a C11
feature.  That union contained a bit-field, which is very unusual since
the C standards answer basically all interesting questions about
bit-fields in unions with "implementation-defined" or "unspecified".
GCC passes these questions further down by saying "Determined by ABI".

This was the only occurrence of a bit-field union member in the whole
NetBSD tree, and it caused the lint diagnostic 41 to be downgraded from
error to warning on 2021-09-17 since this exotic construct is allowed by
the C standards but practically unused.

No binary change.
