Martin reported an issue that directory read could be hung on the
latest -rc kernel with some certain image. The root cause is that
commit baa2c7c97153 ("block: set .bi_max_vecs as actual allocated
vector number") changes .bi_max_vecs behavior. bio->bi_max_vecs
is set as actual allocated vector number rather than the requested
number now.
Let's avoid using .bi_max_vecs completely instead.

Looks good to me, btw, it needs to Cc stable mailing list?

Thanks for your review. <= 5.11 kernels are not impacted.
For now, this only impacts 5.12-rc due to a bio behavior
change (see commit baa2c7c97153). So personally I think
just leave as it is is fine.
Okay, so that's fine if you send pull request before 5.12 formal release. ;)
Thanks,
