In some cases of resetting a VF, the PF would like to first notify the
VF that a reset is impending. This is currently done via
ice_vc_notify_vf_reset. A wrapper to ice_reset_vf, ice_vf_reset_vf, is
used to call this function first before calling ice_reset_vf.

In fact, every single call to ice_vc_notify_vf_reset occurs just prior
to a call to ice_vc_reset_vf.

Now that ice_reset_vf has flags, replace this separate call with an
ICE_VF_RESET_NOTIFY flag. This removes an unnecessary exported function
of ice_vc_notify_vf_reset, and also makes there be a single function to
reset VFs (ice_reset_vf).
