tcp: Explicitly check option length field values in tcp_opt_get()
Reported by Coverity (CWE-606, Untrusted loop bound), and actually
harmless because we'll exit the option-scanning loop if the remaining
length is not enough for a new option, instead of reading past the
header.
In any case, it looks like a good idea to explicitly check for
reasonable values of option lengths.
