ARM: oprofile: fix and simplify init/exit functions

Now that oprofile_arch_exit is only called when the OProfile module
is unloaded, it can assume that init completed successfully and not
have to worry about double frees or releasing NULL perf events.

This patch ensures that oprofile_arch_init fails gracefully on ARM
and simplifies the exit code based on the above.
