KVM: arm64: Only insert reserved ranges when SMCCC filter is used
The reserved ranges are only useful for preventing userspace from
adding a rule that intersects with functions we must handle in KVM. If
userspace never writes to the SMCCC filter than this is all just wasted
work/memory.
Insert reserved ranges on the first call to KVM_ARM_VM_SMCCC_FILTER.
