The fm10k driver was reading the interrupt cause register but then
using the interrupt mask register defines to look at the bits.
The result is that if a fault happens, the driver would never clear
the fault and would get into an infinite cycle of interrupts.
Note: I don't work for Intel or have the hardware manuals (probably
requires NDA anyway), but this looks logical and matches how the
known working Linux driver handles these bits.
