From: Alvin Zhang <alvinx.zh...@intel.com>
If support-multi-driver is enabled, the global registers should not
be configured. But with the correct code base, if creating a flow
with rte_flow API, the global register GLQF_FD_MSK may be changed.
Fixes: cfdfca493cae ("net/i40e: fix multiple driver support")
