Subject: [patch] target: Silence an uninitialized variable warning

I'm getting a static checker warning:

    drivers/target/target_core_sbc.c:1150 sbc_parse_cdb()
    error: uninitialized variable 'size'.

It looks like a possible bug but wouldn't it have shown up in testing?
Anyway let's just silence it by setting size to zero.
