mac80211: partly revert force-mac80211 loss detection

This patch will only force mac80211 loss detection upon ath10k by
masking the driver-specific loss-detection bit.

+Subject: [PATCH] ath10k: always use mac80211 loss detection
+
+ath10k does not report excessive loss in case of broken block-ack
+sessions. The loss is communicated to the host-os, but ath10k does not
+trigger a low-ack events by itself.
+
+The mac80211 framework for loss detection however detects this
+circumstance well in case of ath10k. So use it regardless of ath10k's
+own loss detection mechanism.

-Patching this in mac80211 does allow this hack to be used with any
