powerpc/kprobes: Have optimized_callback() use preempt_enable()

Similar to x86 commit 2e62024c26 ("kprobes/x86: Use preempt_enable()
in optimized_callback()"), change powerpc optprobes to use
preempt_enable() rather than preempt_enable_no_resched() since powerpc
also removed irq disabling for optprobes in commit f72180cc93
("powerpc/kprobes: Do not disable interrupts for optprobes and
kprobes_on_ftrace").
