sctp: Fix crash on free() when using the MSVC binaries
On Windows, if libusrsctp and gstreamer are built with different
C runtimes (CRT), we cannot free memory allocated inside libusrsctp
with the free()
function from gstreamer's CRT.
usrsctp_freedumpbuffer()
simply calls free()
, but because of the
way DLLs work on Windows, it will always call the free function from
the correct CRT.
