[media] DocBook: Add a chapter to describe media errors
There are several errors reported by V4L that aren't described.
They can occur on almost all ioctl's. Instead of adding them
into each ioctl, create a new chapter.
For V4L, the new chapter will automatically be listed on all
places, as there's a macro used everywhere there.
