6773712672 if: fix bio_get stack corruption when bio is on stack 
I am unsure whether this might break compatibility to some
very ancient kernels.

AFAICR, it could have been needed long ago, when some old 32bit
kernels needed kmap().

Anyway, I don't have those old kernels anymore.

This might potentially worsen IO performance somewhat. Please report
any _reproducible_ issues, together with a reproducer.

b6ef899ded Revert "if: remove obsolete merge_bvec_fn()" 
This reverts commit d96b6e3fbf.

Altough newer kernels don't have this anymore, old kernels
need it.

Make it dependend from the kernel version.
