bcache_register(): don't bother with set_blocksize()

Browse Source 
We are not using __bread() anymore and read_cache_page_gfp() doesn't
care about block size.  Moreover, we should *not* change block
size on a device that is currently held exclusive - filesystems
that use buffer cache expect the block numbers to be interpreted
in units set by filesystem.
