[PATCH] VMCI: Fix integer overflow in VMCI handle arrays
The VMCI handle array has an integer overflow in
vmci_handle_arr_append_entry when it tries to expand the array. This can be

limit on the number of doorbell handles that a VM can create in the
hypervisor, and these handles are stored in a handle array.
In this change, we introdu...
