Details:

The way I see it, ERR_IS_FATAL() is only really needed when accept or reading
from a netconn to prevent blocking if the connection has been closed.

Instead of using a generic way and marking errors as FATAL in err.h, we should
fix this in the netconn layer and mark netconns as closed when blocking on
acceptmbox/recvmbox should be prevented.
