x86: setup_smep needs to be __cpuinit
The setup_smep function gets calle at resume time too, and is thus not a
pure __init function. When marked as __init, it gets thrown out after
the kernel has initialized, and when the kernel is suspended and
resumed, the code will no longer be around, and we'll get a nice "kernel
tried to execute NX-protected page" oops because the page is no longer
marked executable.
