KVM: arm64: nv: Fix RESx behaviour of disabled FGTs with negative polarity

The Fine Grained Trap extension is pretty messy as it doesn't
consistently use the same polarity for all trap bits. A bunch
of them, added later in the life of the architecture, have a
*negative* priority.

So if these bits are disabled, they must be RES1 and not RES0.
But that's not what the code implements, making the traps for
these negative trap bits being always on instead of disabled.

Fix the relevant bits, and stick a brown paper bag on my head
for the rest of the day...
