ide: Fix IDE taskfile with cfq scheduler ...
When ide taskfile access is being used (for example with hdparm --security
commands) and cfq scheduler is selected, the scheduler crashes on BUG in
cfq_put_request.
The reason is that the cfq scheduler is tracking counts of read and write
requests separately; the ide-taskfile subsystem allocates a read request and
then flips the flag to make it a write request. The counters in cfq will
mismatch.
This patch changes ide-taskfile to allocate the READ or WRITE request as
required and don't change the flag later.
