staging: gasket: interrupt: remove PCI-MSIX-specific status check

Devices not using MSIX don't use the msix_initialized field, don't
require it to be set in the interrupt system status check. The general
check for interrupts configured that follows can cover both MSIX and
device-managed interrupts.
