pcie_sriov: Remove g_new assertion

Browse Source 
g_new() aborts if the allocation fails so it returns NULL only if the
requested allocation size is zero. register_vfs() makes such an
allocation if NumVFs is zero so it should not assert that g_new()
returns a non-NULL value.

Fixes: 7c0fa8dff8 ("pcie: Add support for Single Root I/O Virtualization (SR/IOV)")
