x86/cpu: Rename cpu_data.x86_mask to cpu_data.x86_stepping
commit b399151cb48db30ad1e0e93dd40d68c6d007b637 upstream.
x86_mask is a confusing name which is hard to associate with the
processor's stepping.
Additionally, correct an indent issue in lib/cpu.c.
[ Backport by Mark Gross to simplify the SRBDS backport ]
