ide: remove ide_do_drive_cmd()

Browse Source 
* Use elv_add_request() instead of __elv_add_request() in ide_do_drive_cmd().

* ide_do_drive_cmd() is used only in ide-{atapi,cd}.c so inline it there.

There should be no functional changes caused by this patch.

* ide_do_drive_cmd - issue IDE special command
* @drive: device to issue command
* @rq: request to issue

* This function issues a special IDE device request

*
* the rq is queued at the head of the request queue, displacing
* the currently-being-processed request and this function
* returns immediately without waiting for the new rq to be
* completed. This is VERY DANGEROUS, and is intended for
* careful use by the ATAPI tape/cdrom driver code.
