jprobes: make struct jprobe.entry a void *



Currently jprobe.entry is a kprobe_opcode_t *, but that's a lie.  On some
platforms it doesn't point to an opcode at all, it points to a function
descriptor.

It's really a pointer to something that the arch code can turn into a function
entry point.  And that's what actually happens, none of the generic code ever
looks at jprobe.entry, it's only ever dereferenced by arch code.

So just make it a void *.
