[PATCH] cfq-iosched: fix problem with barriers and max_depth == 1
CFQ will currently stall when using write barriers and the default max_depth setting of 1, since we artificially need a depth of 2 when pre-pending the first flush. So never deny the barrier request going to the device. This is a regression since 2.6.12, it was found in SUSE testing.
