[media] DocBook: Add a chapter to describe media errors

Browse Source 
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.
