qcacmn: Remove wmi_unified_vdev_restart_send() prototype

Currently wmi_unified_api defines a wmi_unified_vdev_restart_send()
prototype, but there is no implementation of this function. This
discrepancy dates back to the initial introduction of the prototype in
change "qcacmn: Add tlv implementation of common unified API" (Change
Id I7e70b48ef5e1df0c0f81c639579e6eb1a6685dc3). Since this function
does not exist, and in fact has never existed, remove the prototype.

Note that another API, wmi_unified_vdev_start_send(), supports both
start and restart capability.
