CMSIS-DAP: print a debug message when the USB product string cannot be read

As suggested by Stian Skjelstad in a comment in:

http://openocd.zylin.com/#/c/2044/

if the USB product string cannot be read, provide a debug message so
users might get aware of a potential permission problem when looking
at the debug output.

Fix style bug found by Jenkins.
