[SCSI] qla4xxx: ql4_init.c bugfixes 

In qla4xxx_get_ddb_entry() and qla4xxx_add_device_dynamically()
differentiate between a target which has been newly added vs a target
which went offline temporarily and is online again.  In
qla4xxx_build_ddb_list() firmware ddb state needs to be updated by
calling qla4xxx_get_ddb_entry(). Fix qla4x00_pci_config() and clean up
code.
