via-velocity: move residual free rx descriptors count register update
Updates of the RBRDU have two different meanings depending on their
context:
1. the receiving process has not started - the value which is written
into the RBRDU register is supposed to be the free rx descriptors
count (rounded to a multiple of 4)
2. the receiving process is running - the value increments the count
above (sic)
The update is currently issued deep inside the rx replenish chain (see
velocity_give_many_rx_descs).
Let's propagate enough information to the caller so that the rx
replenish functions do not depend on hardware any more.
It is needed to perform the Rx/Tx buffers housekeeping when MTU changes.
