platform/x86: acer-wmi: Fix missing capability check
During the rework of the fan behavior control code in commit
d8e8362b09d3 ("platform/x86: acer-wmi: Fix setting of fan behavior"),
acer_toggle_turbo() was changed to use WMID_gaming_set_fan_behavior()
instead of WMID_gaming_set_u64() when switching the fans to turbo
mode. The new function however does not check if the necessary
capability (ACER_CAP_TURBO_FAN) is actually enabled on a given
machine, causing the driver to potentially access unsupported
features.
Fix this by manually checking if ACER_CAP_TURBO_FAN is enabled
on a given machine before changing the fan mode.
