If the colorspace is specified by userspace we should respect
it and not reset it ourself if we can support it.

Signed-off-by: Thibault Saunier <thibault.saunier@osg.samsung.com>

Changes in v3:
- Do not check values in the g_fmt functions as Andrzej explained in previous review
- Set colorspace if user passed V4L2_COLORSPACE_DEFAULT in

Changes in v2: None
