efinet: enable hardware filters when opening interface

Browse source 
Exclusive open on SNP will close all existing protocol instances which
may disable all receive filters on interface. Reinstall them after we
opened protocol exclusively.

Also follow UEFI specification recommendation and stop interfaces when
closing them:

Unexpected system errors, reboots and hangs can occur if an OS is loaded
and the network devices are not Shutdown() and Stopped().

Closes: 45204
