Joran Dirk Greef a9b107045f Use load acquire semantics when reading the SQPOLL wakeup flag ...

Ensures that the wakeup flag is read after the tail pointer has been
written. It's important to use memory load acquire semantics for the
flags read, otherwise the application and the kernel might not agree on
the consistency of the wakeup flag, leading to I/O starvation.
