Mahavir Jain ab6ad844b1 mbedtls: use errno instead of SO_ERROR for getting socket errors
As per upgrade notes of lwIP v2.1.0:
socket API: according to the standard, SO_ERROR now only returns asynchronous errors.
All other/normal/synchronous errors are (and always were) available via 'errno'.
LWIP_SOCKET_SET_ERRNO has been removed - 'errno' is always set - and required!
