inets: Terminate really gracefully on bad chunk
Without this fix, httpc:request/1 crashes the httpc_handler when an
invalid chunked length header is encountered (since 77acb47):
=ERROR REPORT==== 14-Nov-2015::17:19:30 ===
** Generic server <0.651.0> terminating
** Last message in was {tcp,#Port<0.5714>,
<<"HTTP/1.1 200 ok\r\nTransfer-Encoding:chunked\r\n\r\nåäö\r\n">>}
** When Server state == {state,
[...]
** Reason for termination ==
** {bad_return_value,{error,{chunk_size,"åäö"}}}
