qcacld-3.0: Fix bandwidth vote level for device in monitor mode

Bandwidth level was set correctly to PLD_BUS_WIDTH_VERY_HIGH
but current vote level was not updated for monitor mode.
Due to this during PCI link down the reg writes for SW2WBM
release ring were enqueued in delayed register write work
queue instead of being written directly.

Delay in scheduling the workqueue results in SW2WBM release
ring getting full which results in invoking panic.
Hence update the current vote level along with the bus
bandwidth in HDD open function for monitor mode.
