Sometimes the register status can include interrupts that were masked. We can, for example, get the RF-Kill bit set in the interrupt status register although this interrupt was masked. Then if we get the ALIVE interrupt (for example) that was not masked, we need to *not* service the RF-Kill interrupt. Fix this in the MSI-X interrupt handler.
