Dexuan Cui 191cb91329 Drivers: hv: vmbus: Call hv_synic_free() if hv_synic_alloc() fails
commit ec97e112985c2581ee61854a4b74f080f6cdfc2c upstream.

Commit 572086325c ("Drivers: hv: vmbus: Cleanup synic memory free path")
says "Any memory allocations that succeeded will be freed when the caller
cleans up by calling hv_synic_free()", but if the get_zeroed_page() in
hv_synic_alloc() fails, currently hv_synic_free() is not really called
in vmbus_bus_init(), consequently there will be a memory leak, e.g.
hv_context.hv_numa_map is not freed in the error path. Fix this by
updating the goto labels.
