f2fs: flag as supporting buffered async reads
The f2fs uses generic_file_buffered_read(), which supports buffered async
reads since commit 1a0a7853b901 ("mm: support async buffered reads in
generic_file_buffered_read()").
Let's enable it to match other file-systems. The read performance has been
greatly improved under io_uring:
167M/s -> 234M/s, Increase ratio by 40%
Test w/:
./fio --name=onessd --filename=/data/test/local/io_uring_test
--size=256M --rw=randread --bs=4k --direct=0 --overwrite=0
--numjobs=1 --iodepth=1 --time_based=0 --runtime=10
--ioengine=io_uring --registerfiles --fixedbufs
--gtod_reduce=1 --group_reporting --sqthread_poll=1
