mlxsw: spectrum_router: Avoid potential packets loss

Browse source

[ Upstream commit f7df4923fa ]

When the structure of the LPM tree changes (f.e., due to the addition of
a new prefix), we unbind the old tree and then bind the new one. This
may result in temporary packet loss.

Instead, overwrite the old binding with the new one.
