Don't need cached read index anymore now that packet iterator is used. The iterator has the original read index until the visible read_index is updated.

The function hv_signal_on_read was defined in hyperv.h and only used in one place in ring_buffer code. Clearer to just move it inline there.

This patch addresses the following bugs in the current rescind handling code: 1. Fixes a race condition where we may be invoking hv_process_channel_removal() on an already freed channel. 2. Prevents indefinite wait when rescinding sub-channels by correctly setting the probe_complete state. I would like to thank Dexuan for patiently reviewing earlier versions of this patch and identifying many of the issues fixed here. Greg, please apply this to 4.14-final.

This patch handles the following issues that were observed when we are handling racing channel offer message and rescind message for the same offer: 1. Since the host does not respond to messages on a rescinded channel, in the current code, we could be indefinitely blocked on the vmbus_open() call. 2. When a rescinded channel is being closed, if there is a pending interrupt on the channel, we could end up freeing the channel that the interrupt handler would run on. Signed-off-by: K. Y.
