[efr32] fix otPlatRadioTxDone sometimes not being called (#2549)

Browse Source 
Sometimes when transmission is started RAIL_EVENT_RX_OVERFLOW
happens and then otPlatRadioTxDone is never called.

This commit makes sure the RX FIFO is always drained, even when
transmitting so RAIL_EVENT_RX_OVERFLOW never happens.
