[SCSI] libfc: add local port hook for provider session lookup
The target provider needs a per-instance lookup table or other way to lookup sessions quickly without going through a linear list or serializing too much. Add a simple void * array indexed by FC-4 type to the fc_lport. Signed-off-by: Joe Eykholt <jeykholt@cisco.com> Committed-by: Nicholas A.
