[PATCH] linux-yocto-dev: Ensure we don't reparse the recipe when its not being used (take 2)

[Richard Purdie <richard.purdie@linuxfoundation.org>]

The use of the ${AUTOREV} variable means bitbake would always re-parse the
recipe. This isn't desirable when its disabled so undo the always parsing
flag in this case.
