ethtool: set device channel counts with CHANNELS_SET request
Implement CHANNELS_SET netlink request to set channel counts of a network
device. These are traditionally set with ETHTOOL_SCHANNELS ioctl request.
Like the ioctl implementation, the generic ethtool code checks if supplied
values do not exceed driver defined limits; if they do, first offending
attribute is reported using extack. Checks preventing removing channels
used for RX indirection table or zerocopy AF_XDP socket are also
implemented.
Move ethtool_get_max_rxfh_channel() helper into common.c so that it can be
used by both ioctl and netlink code.
v2:
- fix netdev reference leak in error path (found by Jakub Kicinsky)
