kprobes: treewide: Replace arch_deref_entry_point() with dereference_symbol_descriptor()
~15 years ago kprobes grew the 'arch_deref_entry_point()' __weak function:
3d7e33825d87: ("jprobes: make jprobes a little safer for users")
But this is just open-coded dereference_symbol_descriptor() in essence, and
its obscure nature was causing bugs.
Just use the real thing and remove arch_deref_entry_point().
