This is the SNP interface routine for stopping the interface.
This routine basically retrieves snp structure, checks the SNP state and

@param this context pointer
Changes the state of a network interface from "started" to "stopped."
This function stops a network interface. This call is only valid if the network
interface is in the started state. If the network interface was successfully
stopped, then EFI_SUCCESS will be returned.
@param This A pointer to the EFI_SIMPLE_NETWORK_PROTOCOL instance.
@retval EFI_SUCCESS The network interface was stopped.
@retval EFI_NOT_STARTED The network interface has not been started.
@retval EFI_INVALID_PARAMETER This parameter was NULL or did not point to a valid
EFI_SIMPLE_NETWORK_PROTOCOL structure.
@retval EFI_DEVICE_ERROR The command could not be sent to the network interface.
@retval EFI_UNSUPPORTED This function is not supported by the network interface.
