sfc: remove duplicate up_write on VF filter_sem
Somehow two copies of the line 'up_write(&vf->efx->filter_sem);' got into
efx_ef10_sriov_set_vf_vlan(). This would put the mutex in a bad state and
cause all subsequent down attempts to hang.
Fixes: 671b53eec2ed ("sfc: Ensure down_write(&filter_sem) and up_write() are matched before calling efx_net_open()")
