net/mlx5: Fix HCA caps leak on notifier init failure

mlx5_mdev_init() allocates HCA caps via mlx5_hca_caps_alloc() before
calling mlx5_notifiers_init(). If notifier initialization fails, the
error path jumps to err_hca_caps and skips mlx5_hca_caps_free(), leaking
allocated caps.

Add a dedicated unwind label for notifier-init failure that frees HCA
caps before continuing the existing cleanup sequence.
