USB: cdc-acm: signedness fix
Fix bogus assignment of "unsigned char *" to "char *": preserve
unsignedness. These values are used directly as descriptor lengths
when iterating through the buffer, so this *could* cause oddness
that potentially includes oopsing. (IMO not likely, except as
part of a malicious device...)
Fix the bogus warning in CDC ACM which highlighted this problem
(by showing a negative descriptor type). It uses the undesirable
legacy err() for something that's not even an error; switch to
use dev_dbg, and show descriptor types in hex notation to match
the convention for such codes.
