    cluster/ec: Check xdata to avoid memory leak

    Problem: ec_writev_start calls ec_make_internal_fop_xdata
    to set "yes" in xdata before ec_readv (an internal fop)
    is called for head and tail. Second call to this function
    is overwriting the previous allocated dict_t to "xdata",
    which results in memory leak.

    Solution: In ec_make_internal_fop_xdata, check if *xdata
    is NULL or not to avoid overwriting *xdata.
