[PATCH v1 2/2] wifi: mt76: mt7996: fix register mapping

[Shengyu Qu]

Bypass the entry when ofs is equal to dev->reg.map[i].size.
Without this patch, it would get incorrect register mapping when the CR
address is located at the boundary of an entry.

SDK patch: https://git01.mediatek.com/plugins/gitiles/openwrt/feeds/mtk-openwrt-feeds/+/1a559ba2935fcf54eb1867e6ecd1ef7a2d2d0af8/autobuild/unified/filogic/mac80211/24.10/files/package/kernel/mt76/patches/0008-mtk-mt76-mt7996-fix-register-mapping.patch
