Michael Kelley 57441e0615 Drivers: hv: vmbus: Fix synic per-cpu context initialization

[ Upstream commit f25a7ece08bdb1f2b3c4bbeae942682fc3a99dde ]

If hv_synic_alloc() errors out, the state of the per-cpu context
for some CPUs is unknown since the zero'ing is done as each
CPU is iterated over.  In such case, hv_synic_cleanup() may try to
free memory based on uninitialized values.  Fix this by zero'ing
the per-cpu context for all CPUs before doing any memory
allocations that might fail.
