bpf: Rename bpf_call_summary::num_params to arg_slot_cnt

The field 'num_params' counts the argument registers and outgoing
stack slots a helper or kfunc call takes. The next patch gives a
16-byte parameter two slots, so the name stops describing what the
field holds.

Rename 'num_params' to 'arg_slot_cnt'. No functional change.
