tools: bpftool: maps: close json array on error paths of show
We can't return from the middle of do_show(), because
json_array will not be closed. Break out of the loop.
Note that the error handling after the loop depends on
errno, so no need to set err.
Fixes: 831a0aafe5c3 ("tools: bpftool: add JSON output for `bpftool map *` commands")
