f2fs: add iostat latency tracking for direct IO

Browse source

F2FS did not collect iostat latency for direct IO reads and writes,
hook iomap_dio_ops.submit_io to bind an iostat context and record the
submission timestamp. Replace bi_end_io with f2fs_dio_end_bio() to
collect IO latency on completion before calling back to the original
iomap_dio_bio_end_io(), to add iostat latency tracking support for
F2FS DIO.
