KVM: arm64: Fix nVHE stacktrace VA bits mask
The hypervisor VA space size depends on both the ID map's
(IDMAP_VA_BITS) and the kernel stage-1 (VA_BITS). However, the
hypervisor stacktrace decoding is solely relying on VA_BITS. This is
especially an issue when VA_BITS < IDMAP_VA_BITS (i.e. VA_BITS is
39-bit): the hypervisor may have addresses bigger than the stacktrace is
masking.
Align this mask with hyp_va_bits.
