Xcode: Fix early termination on per-config source file error

In commit v3.1.0-rc1~687^2~4 (cmTarget: Make the source files depend on
the config, 2014-02-13) an early termination case was added to the Xcode
generator.  Fix handling of this case to actually abort all the
generation steps.  Otherwise some of the later steps are attempted
without the preconditions normally established by earlier steps,
possibly leading to a crash.
