acpi/acpigen: Fix buffer length in acpigen_write_name_unicode()

The buffer length is in bytes, and since we are converting from ASCII
to UTF-16, the value written needs to be 2x the string length + null
terminator.

TEST=build/boot google skyrim (frostflow), dump acpi and check bytecode
for correct buffer length preceding unicode strings.
