Subject: AMD_SFH: Removed unused activecontrolstatus member from the
 amd_mp2_dev struct

From: Hans de Goede <hdegoede@redhat.com>

[ Upstream commit a9e54f4b62dcfed4432a5a89b1cd5903737f6e83 ]

This value is only used once inside amd_mp2_get_sensor_num(),
so there is no need to store this in the amd_mp2_dev struct,
amd_mp2_get_sensor_num() can simple use a local variable for this.

Fixes: 4f567b9f8141 ("SFH: PCIe driver to add support of AMD sensor fusion hub")
