scsi: lpfc: Update phba link state conditional before sending CMF_SYNC_WQE

Browse source 
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.
