HID: hid-input: fix stylus battery reporting

Browse Source 
[ Upstream commit 505f394fa2 ]

With commit 4f38821772 hid-input started clearing of "ignored" usages
to avoid using garbage that might have been left in them. However
"battery strength" usages should not be ignored, as we do want to
use them.

Fixes: 4f38821772 ("HID: hid-input: clear unmapped usages")
