scsi: lpfc: Change lpfc_hba hba_flag member into a bitmask

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