oprofile, x86: Simplify init/exit functions
Now, that we only call the exit function if init succeeds with commit: 979048e oprofile: don't call arch exit code from init code on failure we can simplify the x86 init/exit functions too. Variable using_nmi becomes obsolete. Signed-off-by: Robert Richter <robert.richter@amd.com>
