3.0.x : bug in eapsimlib.c : "free" function called on a talloc'ed chunk

[nchaigne]

In src/modules/rlm_eap/libeap/eapsimlib.c, at line 258 (branch 3.0.x) we have:

    /* done with the buffer, free it */
    free(buffer);

This causes a segmentation fault, because allocation was performed through talloc:

buffer = talloc_array(r, uint8_t, hmaclen);

Suggested fix:

    talloc_free(buffer);
