scst: Fix MAINTENANCE IN parsing

Browse Source 
Although I do not know of any initiator that asks for the extended
parameter data format when submitting a REPORT TARGET PORT GROUPS
command, I think it's a good idea to support that data format (i.e.
three most significant bits of the second CDB byte are 001 instead
of 000). The attached patch should implement that. Additionally,
cmd->op_name is set to something more descriptive than
"MAINTENANCE IN" in that patch.
