ice: do not bring the VSI up, if it was down before the XDP setup
After XDP configuration is completed, we bring the interface up
unconditionally, regardless of its state before the call to .ndo_bpf().
Preserve the information whether the interface had to be brought down and
later bring it up only in such case.
