[net-next,v2,2/8] ice: use pci_irq_vector helper function

Commit Message

Piotr Raczynski March 22, 2023, 4:25 p.m. UTC

Currently, driver gets interrupt number directly from ice_pf::msix_entries
array. Use helper function dedicated to do just that.

While at it use a variable to store interrupt number in
ice_free_irq_msix_misc instead of calling the helper function twice.
