[Intel-wired-lan] [PATCH net-next 04/15] iavf: wrap driver state change in crit_section lock

From: Nicholas Nunley <nicholas.d.nunley at intel.com>

The changes to driver state in iavf_disable_vf() should be made inside
the crit_section lock, not outside of it, since the complete configuration
flow needs to be seen as one atomic operation.
