samples/bpf: load_bpf.c make callback fixup more flexible
Do this change before others start to use this callback.
Change map_perf_test_user.c which seems to be the only user.
This patch extends capabilities of commit 9fd63d05f3e8 ("bpf:
Allow bpf sample programs (*_user.c) to change bpf_map_def").
Give fixup callback access to struct bpf_map_data, instead of
only stuct bpf_map_def. This add flexibility to allow userspace
to reassign the map file descriptor. This is very useful when
wanting to share maps between several bpf programs.
