dp83640: free packet queues on remove
commit 8b3408f8ee994973869d8ba32c5bf482bc4ddca4 upstream. If the PHY should disappear (for example, on an USB Ethernet MAC), then the driver would leak any undelivered time stamp packets. This commit fixes the issue by calling the appropriate functions to free any packets left in the transmit and receive queues. The driver first appeared in v3.0.
