> Currently if ice_reset_all_vfs() fails in ice_alloc_vfs() we fail to free some
> resources, reset variables, and return an error value.
> Fix this by adding another unroll case to free the pf->vf array, set the pf-
> >num_alloc_vfs to 0, and return an error code.
> 
> Without this, if ice_reset_all_vfs() fails in ice_alloc_vfs() we will not be able
> to do SRIOV without hard rebooting the system because rmmoding the
> driver does not work.
