x86: kprobes: Remove remove bogus preempt_enable
The CONFIG_PREEMPT=n section of setup_singlestep() contains:
preempt_enable_no_resched();
That's bogus as it is asymetric - no preempt_disable() - and it just
never blew up because preempt_enable_no_resched() is a NOP when
CONFIG_PREEMPT=n. Remove it.
