[Buildroot] [git commit branch/next] boot/barebox: check for config file before calling kconfig-package

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=06d126fdc1813dad84c95c2500f400f45853ffae
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/next

If we check that the user provides a config file after we call to the
kconfig-package infra, the error message we get is the one for the
kconfig-package infra, not the custom error message we want to show to
the user.

So, only call kconfig-package after we do the check.
