usb: core: Clean up SuperSpeed/eUSB2 descriptor validation logging

Core usually prints endpoint addresses with 0x%X format.
Change this code to use it too, instead of just %d.
Particularly for IN, 0x83 seems more readable than 131.

While at that, fix checkpatch warnings about multi-line
quoted strings, as well as missing or doubled whitespace
in those strings.
