[PATCH bpf-next v3 7/7] bpftool: Clean up _bpftool_once_attr() calls in bash completion

[Quentin Monnet <quentin@xxxxxxxxxxxxx>]

In bpftool's bash completion file, function _bpftool_once_attr() is able
to process multiple arguments. There are a few locations where this
function is called multiple times in a row, each time for a single
argument; let's pass all arguments instead to minimize the number of
function calls required for the completion.
