net/ixgbevf: fix promiscuous and allmulti

Browse Source 
The configuration of allmulti and promiscuous modes conflicts
together. For instance, if we enable promiscuous mode, then enable and
disable allmulti, then the promiscuous mode is wrongly disabled.

Fix this behavior by:
- doing nothing when we set/unset allmulti if promiscuous mode is on
- restorting the proper mode (none or allmulti) when we disable
  promiscuous mode
