passthrough_example: make parallel_direct_writes more clearly
Move the parallel_direct_writes enable action to the init function in high level API,
it is more recommended just like commit 8ee553dac. Besides, add some comments to show
that the feature parallel_direct_writes is depend on the feature direct_io (refer to
kernel side patch series to consolidate direct IO, link: https://lwn.net/ml/linux-fsdevel/
20230918150313.3845114-1-bschubert@ddn.com for the reason).
