Chen Qun 126b5df512 block: bugfix: Don't pause vm when NOSPACE EIO happened
When backend disk is FULL and disk IO type is 'dataplane',
QEMU will pause the vm, and this may cause endless-loop in
QEMU main thread if we do the snapshot merge now.

When backend disk is FULL, only reporting an error rather
than pausing the virtual machine.
