mt76: mt7615: fix possible deadlock while mt7615_register_ext_phy()

[ Upstream commit 8c55516de3f9b76b9d9444e7890682ec2efc809f ]

ieee80211_register_hw() is called with rtnl_lock held, and this could be
caused lockdep from a work item that's on a workqueue that is flushed
with the rtnl held.

Move mt7615_register_ext_phy() outside the init_work().
