drivers: usb: nordic: Fix max packet size handling

This commit fixes the issue with non-default max packet size (<64).
The max packet size value was not passed to low-level driver
in norfic hal (nrfx_usbd) causing 64-byte being send regardless of
configured endpoint size. Size mismatch results in communication
error on Linux hosts.
