Prepare mlx4 and mlx5 drivers to have all devlink callbacks called with
devlink instance locked. Change mlx4 driver to use devl_ API where
needed to have devlink reload callbacks locked. Change mlx5 driver to
use devl_ API where needed to have devlink reload and devlink health
callbacks locked.

As mlx5 is the only driver which needed changes to enable calling health
callbacks with devlink instance locked, this patchset also removes
DEVLINK_NL_FLAG_NO_LOCK flag from devlink health callbacks.

This patchset will be followed by a patchset that will remove
DEVLINK_NL_FLAG_NO_LOCK flag from devlink and will remove devlink_mutex.

Jiri Pirko (2):
  net: devlink: remove region snapshot ID tracking dependency on
    devlink->lock
  net: devlink: remove region snapshots list dependency on devlink->lock
