ide: set REQ_PREEMPT request flag in ide_do_drive_cmd() users

* Set REQ_PREEMPT request flag in ide_do_drive_cmd() users
  for ide_preempt and ide_head_wait action types.

* Remove setting REQ_PREEMPT from ide_do_drive_cmd().

While at it:

* Set 'where' variable outside ide_lock.

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

There should be no functional changes caused by this patch.
