scsi: target: spc: Fix RSOC parameter data header size
[ Upstream commit b50532318793d28a7628c1ffc129a2226e83e495 ]
The SPC document states that "The COMMAND DATA LENGTH field indicates the
length in bytes of the command descriptor list".
The length should be subtracted by 4 to represent the length of the
description list, not 3.
