Shut up a clang-analyzer warning

The function appears to be safe, since grow() is called with sensible
arguments in previous functions.  Ideally Clang would be clever enough to
realise this.  Even if N has size MBEDTLS_MPI_MAX_LIMBS, which will
cause the grow to fail, the affected lines in montmul won't be reached.
Having this sanity check can hardly hurt though.
