[libvirt] [PATCH 13/16] Ensure we always read a full buffer in tunnelled migration



The 'nbytes' variable was not re-initialized to the
buffer size on each iteration of the tunnelled migration
loop. While saferead() will ensure a full read, except
on EOF, it is clearer to use the real buffer size

* src/qemu/qemu_migration.c: Always read full buffer of data
