CVE-2024-52532: Infinite loop while reading websocket data

Start a websocket server with libsoup and then run the following test case: stall.c

libsoup will enter into a busy loop and use all the memory of the system until it crashes.

The way to fix it is by validating the data read before iterating the read loop that way if the data is not valid it will already abort.

Here a proposed fix:
