proc_usb_info.txt: Correct documentation about endianness of config descriptors
The config descriptors as read from /proc/bus/usb/BBB/DDD are in *bus* endian
format. Correct proc_usb_info.txt to correctly reflect that.

These files can be read as binary data. The binary data consists
of first the device descriptor, then the descriptors for each
-configuration of the device. Multi-byte fields in the device and
-configuration descriptors, but not other descriptors, are converted
-to host endianness by the kernel. This information is also shown

in text form by the /proc/bus/usb/devices file, described later.
These files may also be used to write user-level drivers for the USB
