ice: Restructure VFs initialization flows

Browse source

This patch restructures how VFs are configured, and resources allocated.
Instead of freeing resources that were never allocated, and resetting
empty VFs that have never been created - the new flow will just allocate
resources for number of requested VFs based on the availability.

During VFs initialization process, global interrupt is disabled, and
rearmed after getting MSIX vectors for VFs. This allows immediate mailbox
communications, instead of delaying it till later and VFs.
PF communications resulted to using polling instead of actual interrupt.
The issue manifested when creating higher number of VFs (128 VFs) per PF.
