ice: fix use-after-free in dynamic port cleanup
ice_dealloc_dynamic_port() uses dyn_port->vsi->idx to erase the dynamic
port from pf->dyn_ports. However, it frees the VSI before reading the
index for the erase, resulting in a use-after-free.
Follow the reverse of the allocation order in ice_alloc_dynamic_port()
by erasing the xarray entry before freeing the VSI.
