From: Lorenzo Bianconi <lorenzo@...nel.org>

[ Upstream commit d81bfb41e30c42531536c5d2baa4d275a8309715 ]

Fix the following sparse warning in mt7615_mac_write_txwi routine:
drivers/net/wireless/mediatek/mt76/mt7615/mac.c:758:17:
	warning: incorrect type in assignment
	expected restricted __le32 [usertype]
	got unsigned long
