ossfuzz: Remove duplicate tcp flags parsing in flow extract target
During a code audit, the flow extraction fuzzer target was seen to be
parsing tcp flags from the fuzzer supplied input twice. This is
probably a typo since the second call to `parse_tcp_flags()` is
identical to the first.
Since a call to `parse_tcp_flags()` parses the Ethernet and IP headers
contained in the packet, the second (buggy) call to `parse_tcp_flags()`
creates an expectation that there is a second set of Ethernet and IP
headers beyond the first which is incorrect. This patch fixes this
problem by removing the duplicate code in question.
