nati_x86_64_defconfig: enable BFQ I/O scheduler

Enable the BFQ (Budget Fair Queueing) I/O scheduler (CONFIG_IOSCHED_BFQ).
BFQ guarantees a high system and application responsiveness, and a low
latency for time-sensitive applications. Details in
Documentation/block/bfq-iosched.rst

Having this I/O scheduler available and select-able at run-time allows
for better real-time system tuning. It also has the side benefit of
avoiding I/O errors due to CPU starvation under heavy real-time loads
which in turn can lead to file systems being re-mounted read-only (see
linked bug).
