net: cdc_ncm: initialize drvflags before usage
ctx->drvflags is checked in the if clause before beeing initialized.
Move initialization before first usage.
Note, that the if clause was backported with commit 75f82a703b30
("cdc_ncm: Set NTB format again after altsetting switch for Huawei
devices") from mainline (upstream commit 2b02c20ce0c2 ("cdc_ncm: Set NTB
format again after altsetting switch for Huawei devices"). In mainline,
the initialization is at the right place before the if clause.
