[PATCH]: Remove PF_MEMDIE as it is redundant

[Juan Quintela]

Hi
        PF_MEMDIE don't have any use in current kernels.  Please
        remove, we only set it in one place, and there we also set
        PF_MEMALLOC.  And we only test it in other place, and we also
        test for PF_MEMALLOC.  This patch has existed in aa for some
        quite time.

        Please apply.

        Later, Juan.
