definition recently moved from blkdev.h to blk-mq.hbreaking both tools/biolatpcts and examples/tracing/biolatpcts. Fix them
by also including blk-mq.h.
blk_account_io_done() got split into two parts - inline condition checks
and the actual accounting with the latter now done in
__blk_account_io_done(). The kprobe attachment needs to be conditionalized
to work across the change. tools/biolatpcts was already updated but
examples/tracing/biolatpcts wasn't. Fix it.
