[ Upstream commit 26d18c75a7496c4c52b0b6789e713dc76ebfbc87 ]
After firmware alive, iwl_trans_pcie_gen2_fw_alive() is called to free the context info. However, on gen3 that will then free the context info with the wrong size.
Since we free this allocation later, let it stick around until the device is stopped for now, freeing some of it earlier is a separate change.
