pgsql: Cleanup more code related to ws2_32.dll loading in src/port/geta

Cleanup more code related to ws2_32.dll loading in src/port/getaddrinfo.c

e2e0219 has removed a code path for Windows 2000 that attempts to load
wship6.dll as fallback if ws2_32.dll is found but not getaddrinfo(),
leaving behind a dangling pointer as the library is freed. However,
there is no point in this check as ws2_32.dll exists since Windows XP,
so just remove the duplicated check.
