net/ice/base: ignore promiscuous already exist

[ upstream commit 6883487 ]

Ignore ERR_ALREADY_EXISTS error when setting promiscuous mode.
This fix is needed because the driver could set promiscuous mode
when it still has not cleared properly.
Promiscuous mode could be set only once, so setting it second
time will be rejected.

Fixes: 60ff6f5 ("net/ice/base: consolidate VF promiscuous mode")
