[PATCH ethtool-next v3 04/16] cmis: Change loop order in cmis_show_dom_chan_lvl_flags()

[Danielle Ratson <danieller@nvidia.com>]

Currently, when printing channel-level flags in ethtool dump, we are
going over the banks, and for each bank, we are printing all the flags.

When JSON support will be added, in per-channel fields we would like to
have an array that each of its elements represents a channel.

Therefore, change the loop order so first we loop over the flags, and
for each one, we print all its channels.
