Subject: [PATCH 4/7] USB: serial: cp210x: clean up flow-control debug message

Shorten the flow-control debug message by abbreviating the field names
and reducing the value width to two characters. The latter improves
readability since all but the least significant byte will almost always
be zero anyway.
