Xing Li cb671aa025 KVM: MIPS: Fix VPN2_MASK definition for variable cpu_vmbits
commit 5816c76dea upstream.

If a CPU support more than 32bit vmbits (which is true for 64bit CPUs),
VPN2_MASK set to fixed 0xffffe000 will lead to a wrong EntryHi in some
functions such as _kvm_mips_host_tlb_inv().

The cpu_vmbits definition of 32bit CPU in cpu-features.h is 31, so we
still use the old definition.
