    cluster/afr: copy loc before passing to syncop
    
    Problem:
    When io-threads is enabled on the client side, io-threads destroys the
    call-stub in which the loc is stored as soon as the c-stack unwinds.
    Because afr is creating a syncop with the address of loc passed in
    setxattr by the time syncop tries to access it, io-threads would have
    already freed the call-stub. This will lead to crash.
    
    Fix:
    Copy loc to frame->local and use it's address.
