[lxc-devel] [PATCH] Fix compile error when building with -Wp, -D_FORTIFY_SOURCE=2

[Dwight Engen]

Fedora by default builds with this flag, and complains about not checking the
return from fchdir. There isn't much we can do if we can't change back to the
original directory, so just log an error message.
