USB: usb.h: reduce syslog clutter [v3]

The the err() / info() / warn() macros in usb.h inserted __FILE__ at
the beginning of the message, which expands to the complete pathname
of the source file within the kernel tree, frequently taking up half
of an 80 character screen line before the actual message even begins.
Use the module name instead.
