[PATCH 2/3] cciss: bug fix for BIG_PASS_THRU

[mikem]

Patch 2 of 3

Applications using CCISS_BIG_PASSTHRU complained that the data written
was zeros.  The code looked alright, but it seems that copy_from_user 
already does a memset on the buffer. Removing it from the pass-through
fixes the apps.

Please consider this for inclusion.
