Subject: [PATCH] cciss: remove unneeded void pointer cast

It's not necessary to cast the result of kmalloc, since void pointers are
promoted to any other type. This also fixes following coccinelle warning:

casting value returned by memory allocation function to (struct cciss_scsi_adapter_data_t *) is useless.
