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.
