From: Wright Feng <wright.feng@xxxxxxxxxxx>
When starting station mode on wlan0 and AP mode on wlan1, the apsta will
be disabled and cause data stall on wlan0(station). The apsta feature
with MCHAN(Multi-Channel Concurrent) or RSDB(Real Simultaneous
Dual-Band) can make STA+AP work on two bands concurrently.
Because of that, we keep apsta enabled if firmware supports MCHAN or
RSDB features
