mwifiex: Small cleanup for handling virtual interface type changes
Handle the obvious invalid virtual interface type changes with a general
check instead of looking at the individual change.
For type changes from P2P_CLIENT to P2P_GO and the other way round, this
changes the behavior slightly: We now still do nothing, but return
-EOPNOTSUPP instead of 0. Now that behavior was incorrect before and
still is, because type changes between these two types are actually
possible and supported, which we'll fix in a following commit.
