usb: gadget: multi: fix error return code in cdc_do_config()

Browse Source 
Fix to return a negative error code from the error handling
case instead of 0, as returned elsewhere in this function.

Introduced by commit 59835a (usb: gadget: multi: use
function framework for ACM.)

Make rndis_do_config() consistent with cdc_do_config() in the way it
handles returning the PTR_ERR(f_acm_*).
