LU-11132 compile: fix LC_BI_BDEV for old kernels

struct bio is located in linux/bio.h in 2.6 kernel serie. LC_BI_BDEV
uses linux/blk_types.h. That makes the configuration check to fail for
those kernels and breaks compiling.

Use linux/bio.h in LC_BI_BDEV so that it worked for both new and all
kernels.
