x86: Be consistent with data size in getuser.S
Consistently use the data register by name and use a sized assembly instruction in getuser.S. There is never any reason to macroize it, and being inconsistent in the same file is just annoying. No actual code change. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
