I'm not entirely sure about it, but it'd be nicer if we actually checked
that it's non-NULL. Just to future-proof the code in case someone adds
another backend.
Please check the other storage_driver.c code... every 'startPool' invocation
is followed by an uncondtional refreshPool call. If a driver is added without
a refreshPool impl, it will crash libvirtd from any avenue that the pool can
be started, so to support a driver like that will need much more work. This is
the one place in the code that checks for backend->refreshPool
