usb: dwc2: Fix inefficient copy of unaligned buffers
Make sure only to copy any actual data rather than the whole buffer,
when releasing the temporary buffer used for unaligned non-isochronous
transfers.
Taken directly from commit 0efd937e27d5e ("USB: ehci-tegra: fix inefficient
copy of unaligned buffers")
Tested with Lantiq xRX200 (MIPS) and RPi Model B Rev 2 (ARM)
