cbfstool: cbfs-mkstage.c: Free `buffer` on error path
Cppcheck warns about a memory leak, present since adding romtool,
the former name of cbfstool, in commit 5d01ec0f.
$ cppcheck --version
Cppcheck 1.59
[…]
[cbfs-mkstage.c:170]: (error) Memory leak: buffer
[…]
Indeed the memory pointed to by `buffer` is not free’d on the error path,
so add `free(buffer)` to fix this.
