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.
