[PATCH net-next 4/4] net: bcmgenet: do not set RX buffer length

[Florian Fainelli <f.fainelli@gmail.com>]

There is no need to set the buffer length during RX buffer allocation
since the hardware will fill that information when the packet is
received, so we are basically forcing a value that will get overwritten.
