powerpc/kprobes: Remove preempt disable around call to get_kprobe() in arch_prepare_kprobe()
arch_prepare_kprobe() is called from register_kprobe() via
prepare_kprobe(), or through register_aggr_kprobe(), both with the
kprobe_mutex held. Per the comment for get_kprobe():
/*
* This routine is called either:
* - under the 'kprobe_mutex' - during kprobe_[un]register().
* OR
* - with preemption disabled - from architecture specific code.
*/
As such, there is no need to disable preemption around the call to
get_kprobe(). Drop the same.
