drm/xe/pf: Fix VF's scheduling priority reporting

When preparing number of impacted VFs parameter for the reporting
helper function, we wrongly ended with adding +1 (representing PF)
twice, since local variable total_vfs was already adjusted. This
resulted in printing a message that was referring to an invalid VF:

 [] xe ... [drm] PF: Enabled 2 of 24 VFs
 [] xe ... [drm] PF: Tile0: GT0: PF..VF25 provisioned with 0(low) scheduling priority

Fix variable initialization and adjust the loop accordingly.
