[ Upstream commit 9b6614e5ead5d19a71893bcca3f1a6569ca0c456 ]
eSR is activated when a chanctx is assigned to more than one link. During eSR activation we should disable RLC for both phys, and configure the FW with a special phy command for both phys. Currently we assign the phy_ctxt to the link only after eSR activation, so RLC is not disabled for the new phy_ctxt, and a cmd is not sent to FW. Fix this by first assigning the new phy_ctxt to the link and then doing the eSR activation.
