It's possible for the driver to send a CMF_SYNC_WQE to nonresponsive firmware during reset of the adapter. The phba link_state conditional check is currently a strict == LPFC_LINK_DOWN, which does not cover initialization states before reaching the LPFC_LINK_UP state. Update the phba->link_state conditional to < LPFC_LINK_UP so that all initialization states are covered before allowing sending CMF_SYNC_WQE. Update taking of the hbalock to be during this link_state check as well.
