KVM: x86 emulator: Use emulator_write_emulated and not emulator_write_std

patch 00b2ef475d4728ca53a2bc788c7978042907e354 in mainline.

emulator_write_std() is not implemented, and calling write_emulated should
work just as well in place of write_std.

Fixes emulator failures with the push r/m instruction.
