[PATCH 20/22] scripts: omap3-usb-loader: fix clang-analyzer false-positive

[Ahmad Fatoum]

clang-analyzer has a heuristic to determine mismatched allocations.
It flags allocating bufsize of chars and assigned it to a pointer
to uint32, although it's ultimately correct.

Let's silence the warning by using the pointee type instead.
