[Intel-wired-lan] [next PATCH S32 03/14] i40e: Move HW flush

[Harshitha Ramamurthy]

From: Akeem G Abodunrin <akeem.g.abodunrin at intel.com>

This patch moves the HW flush routine to the end of the reset flow,
after the completion of writing to the device VFLR registers- the
benefit is to avoid problems in the passthrough routines.
