[ Upstream commit fe69230f05897b3de758427b574fc98025dfc907 ]
When linktype is unknown or kzalloc failed in cfctrl_linkup_request(),
pkt is not released. Add release process to error path.
Fixes: b482cd2053e3 ("net-caif: add CAIF core protocol stack")
Fixes: 8d545c8f958f ("caif: Disconnect without waiting for response")
