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.
