isl_tab_add_sample: return int instead of isl_tab *
In particular, return -1 on error rather than freeing the input isl_tab.
Since an isl_tab is not reference counted, there is no way for
extend_affine_hull to tell its callers that the isl_tab has already
been freed, possible resulting in double frees on errors
in isl_tab_add_sample. Having isl_tab_add_sample return -1 instead
solves this problem.
