mwifiex: fix p2p device doesn't find in scan problem

commit 3d8bd85c2c9e47ed2c82348aa5b6029ed48376ae upstream.

Marvell p2p device disappears from the list of p2p peers on the other
p2p device after disconnection.

It happens due to a bug in driver. When interface is changed from p2p
to station, certain variables(bss_type, bss_role etc.) aren't correctly
updated. This patch corrects them to fix the issue.
