x86: Fix bit corruption at CPU resume time
In commit 78d77df71510 ("x86-64, init: Do not set NX bits on non-NX capable hardware") we added the early_pmd_flags that gets the NX bit set when a CPU supports NX. However, the new variable was marked __initdata, because the main _use_ of this is in an __init routine. However, the bit setting happens from secondary_startup_64(), which is called not only at bootup, but on every secondary CPU start. Including resuming from STR and at CPU hotplug time. So the value cannot be __initdata.
