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.

    LU-10560 osd: bio_integrity_enabled was removed
    
    T10PI bio support patches used bio_integrity_enabled
    which was no longer available in recent kernels.
    Fix this so we can have server support back on 4.13+
    kernels.
