[SCSI] libfcoe: add checking disable flag in FIP_FKA_ADV
When the D bit is set if the FKA_ADV_Period of the FIP Discovery Advertisement, the ENode should not transmit period ENode FIP Keep Alive and VN_Port FIP Keep Alive (FC-BB-5 Rev2, 7.8.3.13). Note that fcf->flags is taken directly from the fip_header, I am claiming one bit for the purpose of the FIP_FKA_Period D bit as FIP_FL_FK_ADV_B, and use FIP_HEADER_FLAGS as bitmask for bits used in fip_header.
