usb: Fix BCD() macro used to set bcdDevice

Browse source 
According to API documentation, the bcdDevice field of the USB
descriptor is supposed to represents the Zephyr kernel major
and minor versions as a binary coded decimal value. However,
when using zephyr 2.0, bcdDevice is shown as 0.00 instead of 2.00.

This is due to a typo in the implementation of the BCD macro in
usb_commond.h. This commit fixes the macro.
