HID: fixup the conflicting keyboard mappings quirk
commit 8e7b341037db1835ee6eea64663013cbfcf33575 upstream. The ignore check that got added in 6ce901eb61 ("HID: input: fix confusion on conflicting mappings") needs to properly check for VARIABLE reports as well (ARRAY reports should be ignored), otherwise legitimate keyboards might break.
