via-velocity: Give RX descriptors to the NIC later on open or MTU change
velocity_open() calls velocity_give_many_rx_descs(), which gives RX
descriptors to the NIC, before installing an interrupt handler or
calling velocity_init_registers(). I think this is very unsafe and it
appears to explain the bug report <http://bugs.debian.org/508527>.
On MTU change, velocity_give_many_rx_descs() is again called before
velocity_init_registers(). I'm not sure whether this is unsafe but
it does look wrong.
Therefore, move the calls to velocity_give_many_rx_descs() after
request_irq() and velocity_init_registers().
