Previously when user tried to allocate to big bio he recieved NULL. As the behavior was changed to `BUG()` passing out of range value is no longer legal. Limiting the requested bio size to BIO_MAX_PAGES (on the older kernels) or to BIO_MAX_VECS (on the newer ones) eliminates the problem as the macros represent the max possible value.
