Yuri Benditovich 2a9f853bb1 netkvm: use per-queue max RX buffers instead of global 
Global value of max RX buffers, shared among queues, is
bad idea. It is especially bad when memory allocation
during queue initialization may fail, for example in case
of driver running under driver verifier. Changing the
global field to per-queue field.
