ice: do not bring the VSI up, if it was down before the XDP setup

Browse Source 
[ Upstream commit 04c7e14e5b0b6227e7b00d7a96ca2f2426ab9171 ]

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.
