KVM: arm64: nv: Work around lack of pauth support in old toolchains

We still support GCC 8.x, and it appears that this toolchain
usually comes with an assembler that does not understand "pauth"
as a valid architectural extension.

This results in the NV ERETAx code breaking the build, as it relies
on this extention to make use of the PACGA instruction (required
by assemblers such as LLVM's).

Work around it by hand-assembling the instruction, which removes the
requirement for any assembler directive.
