drm/hyperv: Fix an error handling path in hyperv_vmbus_probe()
hyperv_setup_vram() calls vmbus_allocate_mmio(). This must be undone in
the error handling path of the probe, as already done in the remove
function.
Fixes: a0ab5abced55 ("drm/hyperv : Removing the restruction of VRAM allocation with PCI bar size")
