fixes symptom CORE-19005 [NETSTAT] crashes when called with -abnop
and no further argument (protocol name missing).
The crash was a regression of
0.4.11-dev-814-g 2b55073360
also meticulously try to match Windows exact screen output and ERRORLEVEL then
instead of e.g.: simply showing the usage help
which means:
ERRORLEVEL 0 for 'netstat -abnop' and displaying Active-string + table header *but without any sane contents*
ERRORLEVEL 1 for 'netstat -abnop bullshit' and displaying usage help
ERRORLEVEL 0 for 'netstat -abnop tcp' and displaying Active-string + table header + contents
ERRORLEVEL 0 for 'netstat -abnop udp' and displaying Active-string + table header + contents
while touching the file do also some unrelated whitespace tweaks.
Within the current ShowTcpTable function logic, tcpTable would be freed twice.
The bug was introduced in b695971c.
Remove the second tcpTable free and fix coverity #1477187. CORE-17831
