ide: use do_rw_taskfile() for ATA_CMD_PACKET commands
* Pass command to ide_issue_pc() and update ->do_request methods in ide-{cd,floppy,tape}.c accordingly. * Convert ide_pktcmd_tf_load() to ide_init_packet_cmd() which just initializes command structure and use do_rw_taskfile() to load ATA_CMD_PACKET commands. While at it: * Rename ide{floppy,tape}_issue_pc() to ide_{floppy,tape}_issue_pc(). There should be no functional changes caused by this patch.
