avcodec/vaapi: mask unused bits in bitplane_present.value
Due to the union construct, unused bits in bitplane_present.value might
be uninitialized even when the used bits are all set to a value.
Masking the unused bits prevents spurious true values when all used
bits are unset, e.g. skipped pictures.
