ide: Make ide_cdrom_prep_fs() initialize the sense buffer pointer
The changes introduced through commit 82ed4db499b8 assume that the sense buffer pointer in struct scsi_request is initialized for all requests - passthrough and filesystem requests. Hence make sure that that pointer is initialized for filesystem requests. Remove the memset() call that clears .cmd because the scsi_req_init() call in ide_initialize_rq() already initializes the .cmd.
