[SCSI] qla2xxx: Collapse RISC-RAM retrieval code during a firmware-dump.
Use the more efficient read-DMA'ble-buffer mailbox commands
rather than reading a single word/dword at a time. We also
remove a bulk of the duplicate mailbox command-handling codes in
favor of more generic read-memory() routines (qla2xxx_dump_ram()
and qla24xx_dump_ram()).
