[POWERPC] spufs: Fix lost events in poll/epoll on mfc
When waiting for I/O events on mfc in an SPU context by using
poll/epoll syscalls, some of the events can be lost because of wrong
order of poll_wait and MFC status checks in the spufs_mfc_poll
function and non-atomic update of tagwait. This fixes the
problem.
