Adrian Hunter 37c6f80898 perf probe: Fix getting the kernel map ...

commit eaeffeb983 upstream.

Since commit 4d99e41365 ("perf machine: Workaround missing maps for
x86 PTI entry trampolines"), perf tools has been creating more than one
kernel map, however 'perf probe' assumed there could be only one.

Fix by using machine__kernel_map() to get the main kernel map.
