[SCSI] libfc: add hook to notify providers of local port changes
When an SCST provider is registered, it needs to know what
local ports are available for configuration as targets.
Add a notifier chain that is invoked when any local port
that is added or deleted.
Maintain a global list of local ports and add an
interator function that calls a given function for
every existing local port. This is used when first
loading a provider.
