Instead of storing the @log at the beginning of rps_dev_flow_table use 5 low order bits of the rps_tag_ptr to store the log of the size. This removes a potential cache line miss (for light traffic). This allows us to switch to one high-order allocation instead of vmalloc() when CONFIG_RFS_ACCEL is not set.
