[PATCH v2 05/15] Drivers: hv: Export vmbus_interrupt for mshv_vtl module

vmbus_interrupt is used in mshv_vtl_main.c to set the SINT vector.
When CONFIG_MSHV_VTL=m and CONFIG_HYPERV_VMBUS=y (built-in), the module
cannot access vmbus_interrupt at load time since it is not exported.

Export it using EXPORT_SYMBOL_FOR_MODULES consistent with the existing
pattern used for vmbus_isr.
