wifi: mac80211: make rate u32 in sta_set_rate_info_rx()

[ Upstream commit 59336e07b287d91dc4ec265e07724e8f7e3d0209 ]

The value of last_rate in ieee80211_sta_rx_stats is degraded from u32 to
u16 after being assigned to rate variable, which causes information loss
in STA_STATS_FIELD_TYPE and later bitfields.
