libbpf: Initialize err in probe_map_create
GCC-11 warns about the possibly unitialized err variable in
probe_map_create:
libbpf_probes.c: In function 'probe_map_create':
libbpf_probes.c:361:38: error: 'err' may be used uninitialized in this function [-Werror=maybe-uninitialized]
361 | return fd < 0 && err == exp_err ? 1 : 0;
