[PATCH 3/3] ide: use __generic_unplug_device() in ide_do_drive_cmd()

[Bartlomiej Zolnierkiewicz]

Call __elv_add_request() with 'plug' == 1 (so the device will be
plugged) and then use __generic_unplug_device() instead of calling
ide_do_request() directly.

This is a preparation for converting IDE to use blk_execute_rq().

while the change should be OK it is really better to handle it before
the real conversion
