cdc_ncm,cdc_mbim: Use NCM by default

Forwarded: not-needed

Devices that support both NCM and MBIM modes should be kept in NCM
mode unless there is userland support for MBIM.

Set the default value of cdc_ncm.prefer_mbim to false and leave it to
userland (modem-manager) to override this with a modprobe.conf file
once it's ready to speak MBIM.
