Angus Gratton 608a487b9c Fix memory leak in ecp_mul_comb() if ecp_precompute_comb() fails ...

In ecp_mul_comb(), if (!p_eq_g && grp->T == NULL) and then ecp_precompute_comb() fails (which can
happen due to OOM), then the new array of points T will be leaked (as it's newly allocated, but
hasn't been asigned to grp->T yet).

Symptom was a memory leak in ECDHE key exchange under low memory conditions.
