staging: hv: use sync_bitops when interacting with the hypervisor
commit 22356585712d1ff08fbfed152edd8b386873b238 upstream.
Locking is required when tweaking bits located in a shared page, use the
sync_ version of bitops. Without this change vmbus_on_event() will miss
events and as a result, vmbus_isr() will not schedule the receive tasklet.
