[Qemu-block] [PATCH 1/1] migration: fix compiler warning on uninitialized variable

[Jeff Cody]

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.
