tools/fit_image.c: Update some return code paths
Coverity has found some problems with the return paths in parts of this
code. We have a case where we were going to the wrong part of the
unwind (open() failed so we cannot close the fd), a case where we were
only free()ing our buf on the error path and finally a case where we did
not munmap in the failure path.
