K. Y. Srinivasan 288fa3e022 Drivers: hv: vmbus: Fix a bug in hv_need_to_signal()
As part of updating the vmbus protocol, the function hv_need_to_signal()
was introduced. This functions helps optimize signalling from guest to
host. The newly added memory barrier is needed to ensure that we correctly
decide when to signal the host.
