Remove unnecessary check for presence of supported EC list

Browse source 
For both client/server the EC curve list is assumed not to be NULL:

- On the client-side, it's assumed when writing the
  supported elliptic curve extension:

    c54ee936d7/library/ssl_cli.c (L316)

- On the server, it is assumed when searching for a
  suitable curve for the ECDHE exchange:

    c54ee936d7/library/ssl_srv.c (L3200)

It is therefore not necessary to check this in mbedtls_ssl_check_curve().
