s390x/pci: Fix interrupt forwarding disable for interpreted devices
Remove the FH_MASK_ENABLE check when disabling interrupt forwarding
during device reset. This check was broken for the default case in
the switch statement above, preventing proper cleanup of interrupt
forwarding.
The pbdev->aif check in s390_pci_kvm_aif_disable() already guards
against double-disabling of interrupt forwarding.
