scsi: qla2xxx: Fix LUN discovery if loop id is not assigned yet by firmware

commit ec322937a7f152d68755dc8316523bf6f831b48f upstream.

This patch fixes LUN discovery when loop ID is not yet assigned by the
firmware during driver load/sg_reset operations. Driver will now search for
new loop id before retrying login.
