nm: Fix typo in size check to determine whether we stack allocated memory.

We allocate GElf_SymX entries, which are larger than plain GElf_Sym structs.
The check to see whether we could use stack allocation used the correct
sizeof (GElf_SymX), but the check to see if we needed to free was using
the incorrect sizeof (GElf_Sym). Which could cause us to leak memory.
