KVM: x86: Exit to user-mode on #UD intercept when emulator requires
commit 61cb57c9ed631c95b54f8e9090c89d18b3695b3c upstream.
Instruction emulation after trapping a #UD exception can result in an
MMIO access, for example when emulating a MOVBE on a processor that
doesn't support the instruction. In this case, the #UD vmexit handler
must exit to user mode, but there wasn't any code to do so. Add it for
both VMX and SVM.
