pimd: logs to help debug leaked channel OIF problems

Browse Source 
Additional protocols were being set on the OIF proto-mask without
logs. Added logs in that area.

Also added start and end logs to ifchannel_delete to help
identify state machine changes that play out as a part of this
event handling.

Ticket: CM-26732
