ice: add bitmap to track VF MSI-X usage

Browse source

Create a bitamp to track MSI-X usage for VFs. The bitmap has the size of
total MSI-X amount on device, because at init time the amount of MSI-X
used by VFs isn't known.

The bitmap is used in follow up patchset to provide a block of
continuous block of MSI-X indexes for each created VF.
