[PATCH v2 07/22] Revert "vga_switcheroo: Add helper function to get the active client"

[Lukas Wunner]

This reverts commit 26814ce68904c9faf977c90edac798156311981f.

The helper function is no longer needed after Dave Airlie's rewrite
of vga_switcheroo_switch_ddc(), the commit introducing it was only
included because 31f23c3d488e ("drm/edid: Switch DDC when reading
the EDID") does not compile without it.
