[PATCH iwl-next 7/10] ice: emit user-visible info message for non-contiguous ETS TC config

[Aleksandr Loktionov <aleksandr.loktionov@intel.com>]

When the remote LLDP peer advertises a non-contiguous TC
mapping the driver silently falls back to a default single-TC
configuration. This leaves the user without any indication of
why their DCB configuration was not honoured.

Print an informational message at the entry of
ice_dcb_noncontig_cfg() so the user knows ETS with
non-contiguous TCs is not supported and that the driver
has fallen back to defaults.
