ide-atapi: convert ide-{floppy,tape} to using preallocated sense buffer
Since we're issuing REQ_TYPE_SENSE now we need to allow those types of
rqs in the ->do_request callbacks. As a future improvement, sense_len
assignment might be unified across all ATAPI devices. Borislav to
check with specs and test.
As a result, get rid of ide_queue_pc_head() and
drive->request_sense_rq.
tj: * Init request sense ide_atapi_pc from sense request. In the
longer timer, it would probably better to fold
ide_create_request_sense_cmd() into its only current user -
ide_floppy_get_format_progress().
* ide_retry_pc() no longer takes @disk.
