net/mlx5: Fix missing devlink lock in SRIOV enable error path

Browse source

[ Upstream commit 60253042c0 ]

The cited commit miss to add locking in the error path of
mlx5_sriov_enable(). When pci_enable_sriov() fails,
mlx5_device_disable_sriov() is called to clean up. This cleanup function
now expects to be called with the devlink instance lock held.

Add the missing devl_lock(devlink) and devl_unlock(devlink)
