64420d7ce7 Remove blkdev_can_hndl_bio() function 
This check will always return 0, as none of kernel versions supported
by Open CAS sets a barrier flag in for bio. Those flags are exclusive to
struct request, which is no longer used by Open CAS.

38bef1f7fe Integrate kmemleak into CAS 
Kmemleak is a tool which allows to detect memory leaks in kernel. It requires
`CONFIG_DEBUG_KMEMLEAK` to be enabled during kernel compilation. Otherwise all
the kmemleak_* functions are NOPs.
