Revert "net: fix cpu_max_bits_warn() usage in netif_attrmask_next{,_and}"

This reverts commit 854701ba4c39afae2362ba19a580c461cb183e4f.

We have more violations around, which leads to:

  WARNING: CPU: 2 PID: 1 at include/linux/cpumask.h:110 __netif_set_xps_queue+0x14e/0x770

Let's back this out and retry with a larger clean up in -next.
