media: VPU: mediatek: don't pass an unused parameter
The load_requested_vpu() function returns a freed vpu_fw pointer. It's
not used so it doesn't cause any problems, but Smatch complains about
it:
drivers/media/platform/mtk-vpu/mtk_vpu.c:578 vpu_load_firmware()
warn: passing freed memory 'vpu_fw'
We can clean up the code a bit and silence the static checker warning
by not passing the parameter at all.
