sock: Error out if setting of the system socket memory fails
Currently we ignore the return value of the write() calls to /proc/sys/net/core/{r,w}mem_{default,max} in set_system_socket_mem(). Better check the return value and notify the user about it. This also fixes a clang compiler warning about a variable explicitely assigned to itself. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
