sh: kprobes: Merge arch_copy_kprobe() into arch_prepare_kprobe()
arch/sh/kernel/kprobes.c:52:16: warning: no previous prototype for 'arch_copy_kprobe' [-Wmissing-prototypes]
Although SH kprobes support was only merged in v2.6.28, it missed the
earlier removal of the arch_copy_kprobe() callback in v2.6.15.
Based on the powerpc part of commit 49a2a1b83ba6fa40 ("[PATCH] kprobes:
changed from using spinlock to mutex").
Fixes: d39f5450146ff39f ("sh: Add kprobes support.")
