scsi: scsi_transport_fc: Introduce encryption group in fc_rport attribute

Introduce a new structure for reporting an encrypted session over an
fc_rport.  The encryption group is added as an attribute in struct
fc_rport and reports information in fc_encryption_info.  This structure
contains a status member variable, which stores a bit value indicating
an encrypted session.
