[ Upstream commit b6193d7030e3c59f1d4c75648c9c8fa40cad2bcd ]
Allocation failure is outside the critical lock section and should
return immediately rather than jumping to the unlock section.
Also unlock as soon as required and remove the now redundant jump label.
Fixes: 80a2a9026b24 ("net/mlx5e: Add a lock on tir list")
