[PATCH AUTOSEL 5.7 260/274] ice: Fix inability to set channels when down

[ Upstream commit 765dd7a1827c687b782e6ab3dd6daf4d13a4780f ]

Currently the driver prevents a user from doing
modprobe ice
ethtool -L eth0 combined 5
ip link set eth0 up

The ethtool command fails, because the driver is checking to see if the
interface is down before allowing the get_channels to proceed (even for
a set_channels).

Remove this check and allow the user to configure the interface
before bringing it up, which is a much better usability case.
