scsi: lpfc: Relocate clearing initial phba flags from link up to link down hdlr

Port wide initialization flags FLOGI_ISSUED and RHBA_CMPL make more sense
to be cleared upon a link down event rather than waiting for a link up
event.  By moving clearing of these initializatin flags to a link down
handler, future confusion on the state of initialization is avoided.
