avformat/os_support: check invalid socket value correctly on Windows

Browse Source 
SOCKET defined in winsock2.h is unsigned and invalid value is defined as
INVALID_SOCKET. Check this explicity to avoid compiler warnings.

See: https://learn.microsoft.com/en-us/windows/win32/winsock/socket-data-type-2
