    migration: fix compiler warning on uninitialized variable
    
    Some older GCC versions (e.g. 4.4.7) report a warning on an
    uninitialized variable for 'request', even though all possible code
    paths that reference 'request' will be initialized.   To appease
    these versions, initialize the variable to 0.
