tools: bpftool: fix infinite loop in map create
[ Upstream commit 8694d8c1f82cccec9380e0d3720b84eee315dfb7 ]
"bpftool map create" has an infinite loop on "while (argc)". The error
case is missing.
Symptoms: when forgetting to type the keyword 'type' in front of 'hash':
$ sudo bpftool map create /sys/fs/bpf/dir/foobar hash key 8 value 8 entries 128
(infinite loop, taking all the CPU)
^C
After the patch:
$ sudo bpftool map create /sys/fs/bpf/dir/foobar hash key 8 value 8 entries 128
Error: unknown arg hash
Fixes: 0b592b5a01be ("tools: bpftool: add map create command")
