d/p/debian/cdc_ncm-cdc_mbim-use-ncm-by-default.patch: drop

cdc_ncm prefer_mbim was originally disabled in 2013 https://lists.debian.org/debian-kernel/2013/03/msg00611.html because it interfered with... some? modems? It doesn't even really say that.

It's been a decade, so userland will have support for MBIM.

"Once your package has support for MBIM, you should enable it in the kernel by installing a uniquely named file in /lib/modprobe.d containing cdc_ncm prefer_mbim=Y" but no package actually does.

Ubuntu ships kernels without this patch.

This patch actively harms end-users; it took this user over a week of debugging modemmanager and then the kernel to establish a reliable connection: https://duckpon.de/@0x47df/statuses/01JFTPJXZFPHTMXG0TDZPRWGMV https://duckpon.de/@0x47df/statuses/01JFTRQ2TZKZWYKSTCD42BP624 https://duckpon.de/@0x47df/statuses/01JFZ5CJRFEFK3987XVR2JP65X
