Which driver are you using? Which operation fails?

p2p_find is always performed in P2P Device role. Whether it is issued on
a control interface for another interface should not really matter much
and it could be more convenient to just route the request to the correct
instance within wpa_supplicant instead of rejecting it. I'm not sure
whether there could be external programs that end up using a random
control interface by not specifying any, so there is some risk of
regressions with this type of changes. The new global control interface
design avoids this, but similar redirection of the control interface
command could be used here as well.
