media: vivid: fix assignment of dev->fbuf_out_flags

[ Upstream commit 5cde22fcc7271812a7944c47b40100df15908358 ]

Currently the chroma_flags and alpha_flags are being zero'd with a bit-wise
mask and the following statement should be bit-wise or'ing in the new flag
bits but instead is making a direct assignment.  Fix this by using the |=
operator rather than an assignment.
