    Move memory barrier in UnlockBufHdr to before releasing the lock.
    Andres Freund authored 
    This bug appears to have been introduced late in the development of
48354581 ("Allow Pin/UnpinBuffer to operate in a lockfree
manner.").

Found while debugging a bug which turned out to be independent of the
commit mentioned above.
