md: fix mssing blktrace bio split events

Browse source

commit 22f166218f upstream.

If bio is split by internal handling like chunksize or badblocks, the
corresponding trace_block_split() is missing, resulting in blktrace
inability to catch BIO split events and making it harder to analyze the
BIO sequence.
