During tx rings configuration default XPS queue config is set and
__I40E_TX_XPS_INIT_DONE is locked. __I40E_TX_XPS_INIT_DONE state is
cleared and set again with default mapping only during queues build,
it means after first setup or reset with queues rebuild. (i.e.
ethtool -L <interface> combined <number>) After other resets (i.e.
ethtool -t <interface>) XPS_INIT_DONE is not cleared and those default
maps cannot be set again. It results in cleared xps_cpus mapping
until queues are not rebuild or mapping is not set by user.

Add clearing __I40E_TX_XPS_INIT_DONE state during reset to let
the driver set xps_cpus to defaults again after it was cleared.
