hw-mgmt: init: Blacklist cdc_subset network driver

Initialization of usb network interface on BMC enabled systems occasionally results in the following error messages: cdc_subset: probe of 1-2.1:1.0 failed with error -22 cdc_ether: probe of 1-2.1:1.0 failed with error -16 Since both cdc_subset and cdc_ether drivers can handle usb network interface between host CPU and BMC, blacklist the cdc_subset driver to make sure that only cdc_ether driver is loaded. This fixes the error messages above. Bug: 4260024 Signed-off-by: Felix Radensky <[email protected]>
