scsi: lpfc: Change lpfc_nodelist nlp_flag member into a bitmask

In attempt to reduce the amount of unnecessary ndlp->lock acquisitions
in the lpfc driver, change nlpa_flag into an unsigned long bitmask and
use clear_bit/test_bit bitwise atomic APIs instead of reliance on
ndlp->lock for synchronization.
