From: Jakub Kicinski <jakub.kicinski@xxxxxxxxxxxxx> [ Upstream commit 62ef81d5632634d5e310ed25b9b940b2b6612b46 ] If device supports offload, but offload fails tls_set_device_offload_rx() will call tls_sw_free_resources_rx() which (unhelpfully) releases and reacquires the socket lock. For a small fix release and reacquire the device_offload_lock.
