libata: Fix regression when the NCQ Send and Receive log page is absent 2015-08-03T16:29:11+00:00 Martin K.

Commit 5d3abf8ff67f ("libata: Fall back to unqueued READ LOG EXT if the DMA variant fails") allowed us to fall back to the unqueued READ LOG variant if the queued version failed. However, if the device did not support the page at all we would end up looping due to a merge snafu. Ensure we only take the fallback path once. Signed-off-by: Martin K.

I have a ST4000DM000 disk. If Linux is booted while the disk is spun down, the command that sets transfer mode causes the disk to spin up.
