llc_sap_add_socket() takes a SAP reference for each socket added to a SAP, and llc_sap_remove_socket() releases it. llc_create_incoming_sock() takes an additional SAP reference after adding the child socket. This extra reference was balanced by an explicit llc_sap_put() in llc_ui_release() until commit3100aa9d74("llc: fix SAP reference counting w.r.t. socket handling") removed that put. The corresponding hold in the accept path was left behind. When such a child socket is removed, only the reference taken by llc_sap_add_socket() is released. The extra reference keeps the SAP alive after its last socket is removed. Remove the obsolete hold.
