drm/amd/display: fix the return of the uninitialized value in ret
Currently if stream->signal is neither SIGNAL_TYPE_DISPLAY_PORT_MST or
SIGNAL_TYPE_DISPLAY_PORT then variable ret is uninitialized and this is
checked for > 0 at the end of the function. Ret should be initialized,
I believe setting it to zero is a correct default.
Addresses-Coverity: ("Uninitialized scalar variable")
Fixes: bd0c064c161c ("drm/amd/display: Add return code instead of boolean for future use")
