[PATCH] ethdev: keep promiscuous/allmulti value before enabling

[Sunyang Wu <sunyang.wu@jaguarmicro.com>]

The values of the promiscuous and allmulticast variables
are set after calling the driver, according to the return value.

Fixes: 400d75818266 ("ethdev: check device promiscuous state")
de5ccf0775ae ("ethdev:do nothing if all-multicast mode is applied
again")
