Stanislav Kinsbursky 2dc958fa2f ipc: set msg back to -EAGAIN if copy wasn't performed ... Make sure that msg pointer is set back to error value in case of MSG_COPY flag is set and desired message to copy wasn't found. This garantees that msg is either a error pointer or a copy address. Otherwise the last message in queue will be freed without unlinking from the queue (which leads to memory corruption) and the dummy allocated copy won't be released.
