Hash :fc568ff0 Message :Deal with partial writes on SSL write
SSL write may do partial writes in some cases. For example, document
of mbedtls_ssl_write says:
If the return value is non-negative but less than length, the function
must be called again with updated arguments: buf + ret, len - ret
(if ret is the return value) until it returns a value equal to the
last 'len' argument.
In case of partial writes, we should continue writing the same chain of
buffer, not the next chain.
