net/ice: fix DCF port statistics

[ upstream commit 70aef239d0de6b2048aecb1220da1d78edb75168 ]

Call 'ice_dcf_stats_reset' during the initialization of the DCF port in
order to clear any statistics that may exist from the last use of the DCF
and to avoid statistics errors.

Fixes: 7564d55 ("net/ice: add DCF hardware initialization")
