b9110635c1 cas_cache: fix "blk_update_request: operation not supported" error 
A write request with the REQ_RAHEAD flag enabled cause the nvme driver
to send a write command with access frequency value that is reserved
(at least on specification version 1.4c). NVME devices might fail this
write command with an unsupported error. So we now clear the request's
flag based on its direction.

4753374b1b Change CAS_BIO_MAX_VECS value 
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.
