wifi: mt76: fix potential memory leak in mt76_wmac_probe()

Browse Source 
[ Upstream commit 42754b7de2b1a2cf116c5e3f1e8e78392f4ed700 ]

In mt76_wmac_probe(), when the mt76_alloc_device() call succeeds, memory
is allocated for both struct ieee80211_hw and a workqueue. However, on
the error path, the workqueue is not freed. Fix that by calling
mt76_free_device() on the error path.

Fixes: c8846e1015 ("mt76: add driver for MT7603E and MT7628/7688")
