usb: gadget: f_hid: fix SuperSpeed descriptors

When adding dynamic configuration for bInterval, the value was removed
from the static SuperSpeed endpoint descriptors but was not set from the
configured value in hidg_bind().  Thus at SuperSpeed the interrupt
endpoints have bInterval as zero which is not valid per the USB
specification.

Add the missing setting for SuperSpeed endpoints.
