qcacmn: Avoid REO destination change when IPA enabled in P2P mode

In cases where one of the interfaces is a P2P-GO and
IPA has been enabled, the P2P connection establishment
fails.

When IPA is enabled, the REO destination is changed to REO4
which can be reaped only by IPA module. But in case of P2P-GO
interface in operation, this change in configuration causes
all the RX packets to be stalled due to incorrect REO configuration.

Hence, to avoid this case, do not change the REO dest config
when the interface subtype is P2P.
