Fix the following samples/bpf build error appeared after the
introduction of bpf_map_create() in libbpf:
CC samples/bpf/fds_example.o
samples/bpf/fds_example.c:49:12: error: static declaration of 'bpf_map_create' follows non-static declaration
static int bpf_map_create(void)
^
samples/bpf/libbpf/include/bpf/bpf.h:55:16: note: previous declaration is here
LIBBPF_API int bpf_map_create(enum bpf_map_type map_type,
^
samples/bpf/fds_example.c:82:23: error: too few arguments to function call, expected 6, have 0
fd = bpf_map_create();
~~~~~~~~~~~~~~ ^
samples/bpf/libbpf/include/bpf/bpf.h:55:16: note: 'bpf_map_create' declared here
LIBBPF_API int bpf_map_create(enum bpf_map_type map_type,
^
2 errors generated.
fds_example by accident has a static function with the same name.
It's not worth it to separate a single call into its own function,
so just embed it.
