ionic: set station addr only if needed

Browse Source 
The code was working too hard and in some cases was trying to
delete filters that weren't there, generating a potentially
misleading error message.
    IONIC_CMD_RX_FILTER_DEL (32) failed: IONIC_RC_ENOENT (-2)

Fixes: 2a654540be ("ionic: Add Rx filter and rx_mode ndo support")
