Subject: mwifiex: set adapter->dev before starting to use mwifiex_dbg()

From: Brian Norris <briannorris@chromium.org>

commit ba1c7e45ec224cc8d2df33ecaee1946d48e79231 upstream.

The mwifiex_dbg() log handler utilizes the struct device in
adapter->dev. Without it, it decides not to print anything.

As of commit 2e02b5814217 ("mwifiex: Allow mwifiex early access to device
structure"), we started assigning that pointer only after we finished
mwifiex_register() -- this effectively neuters any mwifiex_dbg() logging
done before this point.

Let's move the device assignment into mwifiex_register().
