bpftool: Fix print error when show bpf map
If there is no btf_id or frozen, it will not show the pids, but the pids don't
depend on any one of them.
Below is the result after this change:
$ ./bpftool map show
2: lpm_trie flags 0x1
key 8B value 8B max_entries 1 memlock 4096B
pids systemd(1)
3: lpm_trie flags 0x1
key 20B value 8B max_entries 1 memlock 4096B
pids systemd(1)
While before this change, the 'pids systemd(1)' can't be displayed.
Fixes: 9330986c0300 ("bpf: Add bloom filter map implementation")
