brcmfmac: fix setting of station info chains bitmask
[ Upstream commit feb45643762172110cb3a44f99dd54304f33b711 ]
The sinfo->chains field is a bitmask for filled values in chain_signal
and chain_signal_avg, not a count. Treat it as such so that the driver
can properly report per-chain RSSI information.
Before (MIMO mode):
$ iw dev wlan0 station dump
...
signal: -51 [-51] dBm
After (MIMO mode):
$ iw dev wlan0 station dump
...
signal: -53 [-53, -54] dBm
Fixes: cae355dc90db ("brcmfmac: Add RSSI information to get_station.")
