wifi: iwlwifi: mvm: modify link instead of removing it during csa
During CSA the PHY used by the link is changing, So the driver
needs to modify the links phy to the FW. Currently the driver is doing
it by removing the link and adding a new one with the new phy_id, but the
FW expects the link only to be modified. Fix this by modifying the links
phy_id instead of removing it and adding a new one
