esp: accumulate SCSI commands for PDMA transfers in cmdbuf instead of pdma_buf
ESP SCSI commands are already accumulated in cmdbuf and so there is no need to
keep a separate pdma_buf buffer. Accumulate SCSI commands for PDMA transfers in
cmdbuf instead of pdma_buf so update cmdlen accordingly and change pdma_origin
for PDMA transfers to CMD which allows the PDMA origin to be removed.
This commit also removes a stray memcpy() from get_cmd() which is a no-op because
cmdlen is always zero at the start of a command.
Notionally the removal of pdma_buf from vmstate_esp_pdma also breaks migration
compatibility for the PDMA subsection until its complete removal by the end of
the series.
