KVM: fix kvm_fix_hypercall() to return X86EMUL_*
This patch fixes kvm_fix_hypercall() to propagate X86EMUL_* info generated by emulator_write_emulated() to its callers: suggested by Marcelo. The effect of this is x86_emulate_insn() will begin to handle the page faults which occur in emulator_write_emulated(): this should be OK because emulator_write_emulated_onepage() always injects page fault when emulator_write_emulated() returns X86EMUL_PROPAGATE_FAULT.
