ide: fix LOCKDEP warning
commit 295f00042aaf6b553b5f37348f89bab463d4a469 ("ide: don't execute the next queued command from the hard-IRQ context") overlooked that ide_do_drive_cmd() (used for REQUEST SENSE command handling) may still invoke do_ide_request() (->request_fn) in the hard-IRQ context through blk_start_queueing(). This resulted in a LOCKDEP warning after commit b599bc7a1199419e122cb2e9ec6b0fa2cfbbc17b ("ide: use per-device request queue locks (v2)"). Since calling blk_start_queuing() in ide_do_drive_cmd() doesn't make much sense as the port is already marked as busy (so the execution of the new command will be deferred anyway) then just remove it fixing LOCKDEP warning and saving some CPU cycles at the same time.
