[PATCH bpf-next v1] bpf,arena: Rename the kfunc set variable

[Haiyue Wang]

Rename the kfunc set variable to specify the 'arena' function scope,
although the 'UNSPEC' type BPF program is mapped to 'COMMON' hook.

And there is 'common_kfunc_set' defined for real 'common' function in
file 'kernel/bpf/helpers.c'.
