[PATCH 5/5] sfc: add missing annotation for efx_ef10_try_update_nic_stats_vf()

[Jules Irenge]

Sparse reports a warning at efx_ef10_try_update_nic_stats_vf()
warning: context imbalance in efx_ef10_try_update_nic_stats_vf()
        - unexpected unlock
The root cause is the missing annotation at
efx_ef10_try_update_nic_stats_vf()
Add the missing _must_hold(&efx->stats_lock) annotation
