    Fix the pNFS flexible file layout client for servers with small write size. · 7477442f

    The code in nfscl_dofflayout() loops when a flexible file layout server
    provides a small write data limit (no extant server is known to do this).
    If/when it looped, it erroneously reused the "drpc" argument for the
    mirror worker thread, corrupting it.
    This patch fixes the problem by only using the calling thread after the
    first loop iteration.
    Found during testing by simulating a server with a small write size.
    Since no extant pNFS server is known to provide a small write size,
    this fix it not needed in practice at this time.
