EmbeddedPkg/Lan9118Dxe: Rework filter init, enabling and disabling

Correct the setting of the hardware filters according to what it asked
to the driver through the ReceiveFilters() interface function.

Keep track of the hardware settings in the "ReceiveFilterSetting" field of
 the EFI_SIMPLE_NETWORK_MODE structure.

From now, after initialization, all filters are disabled and thus no packet
received.
