media: vimc: cap: check v4l2_fill_pixfmt return value
v4l2_fill_pixfmt() returns -EINVAL if the pixelformat used as parameter is invalid or if the user is trying to use a multiplanar format with the singleplanar API. Currently, the vimc_cap_try_fmt_vid_cap() returns such value, but vimc_cap_s_fmt_vid_cap() is ignoring it. Fix that and returns an error value if vimc_cap_try_fmt_vid_cap() has failed.
