Based on the information given to this driver (via the xmit_more skb flag),
we can defer signaling the host if more packets are on the way. This will help
make the host more efficient since it can potentially process a larger batch of
packets. Implement this optimization.

Set the SRB flags correctly when there is no data transfer. Without this change
some IHV drivers will fail valid commands such as TEST_UNIT_READY.

next_oc and num_sc fields of struct vmbus_channel deserve a description. Move
them closer to sc_list as these fields are related to it.

It is unlikely that that host will ask us to close only one subchannel for a
device but let's be consistent. Do both num_sc++ and num_sc-- with
channel->lock to be on the safe side.
