s390/pci: Do not mask MSI[-X] entries on teardown
The PCI core already ensures that the MSI[-X] state is correct when MSI[-X] is disabled. For MSI the reset state is all entries unmasked and for MSI-X all vectors are masked. S390 masks all MSI entries and masks the already masked MSI-X entries again. Remove it and let the device in the correct state.
