net: cdc_ncm: fix control message ordering
This is a context modified revert of commit 6a9612e2cb22 ("net: cdc_ncm: remove ncm_parm field") which introduced a NCM specification violation, causing setup errors for some devices. These errors resulted in the device and host disagreeing about shared settings, with complete failure to communicate as the end result. The NCM specification require that many of the NCM specific control reuests are sent only while the NCM Data Interface is in alternate setting 0. Reverting the commit ensures that we follow this requirement.
