drm/bridge: Avoid uninitialized variable warning
This code works, but technically it uses "num_in_bus_fmts" before it
has been initialized so it leads to static checker warnings and probably
KMEMsan warnings at run time. Initialize the variable to zero to
silence the warning.
Fixes: f32df58acc68 ("drm/bridge: Add the necessary bits to support bus format negotiation")
