Some uses blk_put_request asymmetrically, that is, they uses it with
requests that not allocated by blk_get_request. As a result,
blk_put_request has a hack to catch a NULL request_queue. Now such
callers are fixed (they use blk_get_request properly). So we can
safely remove the hack in blk_put_request.

pd_special_command uses blk_put_request with struct request on the
stack. As a result, blk_put_request needs a hack to catch a NULL
request_queue. This converts pd_special_command to use
blk_execute_rq.

ide_cd_init_rq is not used by ide-cd_ioctl any more. Only
cdrom_queue_request_sense use it. This converts
cdrom_queue_request_sense to use blk_rq_init directly and removes
ide_cd_init_rq.

For blk_pm_resume_request() requests (which are used only by IDE subsystem
currently) the queue is stopped so we need to call ->request_fn explicitly.
Thanks to:
- Rafael for reporting/bisecting the bug
- Borislav/Rafael for testing the fix
This is a preparation for converting IDE to use blk_execute_rq().

This converts ide_cd_queue_pc to use blk_execute_rq, necessitating
changing the ide_cd_queue_pc prototype into a form that doesn't takes
a pointer to request struct. ide_cd_queue_pc works like scsi_execute.

* 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.
v2:
* For blk_pm_resume_request() requests the queue is stopped so we
need to call ->request_fn explicitly.

Replace the FIT() macro with the kernel-provided clamp_val() macro.
FIT was always being called with a member of a struct ide_timing,
which are shorts, and constant constraints for the min and max.
Thus we can use clamp_val, rather than clamp_t.

Since ide_driveid_update() uses polling to execute the IDENTIFY DEVICE command
but clears nIEN bit in the control register and doesn't mask the IDE interrupt,
the latter does happen and lead to the corresponding message to appear:
ide0: unexpected interrupt, status=0x58, count=1
when e.g. running hdparm with option -X with a non-PCI IDE driver...
