KVM: arm64: nv: Return correct RES0 bits for FGT registers

[ Upstream commit 2eb80a2eee18762a33aa770d742d64fe47852c7e ]

We had extended the sysreg masking infrastructure to more general
registers, instead of restricting it to VNCR-backed registers, since
commit a0162020095e ("KVM: arm64: Extend masking facility to arbitrary
registers"). Fix kvm_get_sysreg_res0() to reflect this fact.

Note that we're sure that we only deal with FGT registers in
kvm_get_sysreg_res0(), the

	if (sr < __VNCR_START__)

is actually a never false, which should probably be removed later.
