[libvirt] [PATCH] qemu: fix a typo on qemuDomainSetBlkioParameters

[ajia at redhat.com]

From: Alex Jia <ajia at redhat.com>

It should be a copy-paste error, the result is programming will result in an 
infinite loop again due to without iterating 'j' variable. 

* src/qemu/qemu_driver.c: fix a typo on qemuDomainSetBlkioParameters.
