[PATCH 5.17 0562/1126] iwlwifi: mvm: fix off by one in iwl_mvm_stat_iterator_all_macs()

[Greg Kroah-Hartman]

From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>

[ Upstream commit f1cbb0a8ca9db80c086009c88c71464ac50f50a2 ]

Change the comparison from ">" to ">=" to avoid accessing one element
beyond the end of the ->per_mac_stats[] array.

Fixes: 6324c173ff4a ("iwlwifi: mvm: add support for statistics update version 15")
