target: Use FD_MAX_SECTORS/FD_BLOCKSIZE for blockdevs using fileio
We can still see the error reported in https://patchwork.kernel.org/patch/2338981/ when using fileio backed by a block device. I'm assuming this will get us past that error (from sbc_parse_cdb), and also assuming it's OK to have our max_sectors be larger than the block's queue max hw sectors?
