net: smc91c111: flush packets on RCR register changes
The SOFT_RST or RXEN in the control register can be used as a condition to unblock the net layer via can_receive(). So check for possible flushes on RCR changes. This will drop all pending packets on soft reset or disable which is the functional intent of the can_receive() logic.
