Patch 1 adds the logging of important state changes to enable SMC-R
users to detect SMC-R link groups that are not redundant and require
user actions. Patch 2 is a contribution to clean up an unused inline
function.

Print to system log when SMC links are available or go down, link group
state changes or pnetids are applied to and removed from devices.
The log entries are triggered by either user configuration actions or
adapter activation/deactivation events and are not expected to happen
often. The entries help SMC users to keep track of the SMC link group
status and to detect when actions are needed (like to add replacements
for failed adapters).
