[PATCH v1 1/2] wifi: mt76: mt7915: 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/+/3627eb7e975959ed944e333e383e92f01ac5cdb9/autobuild/autobuild_5.4_mac80211_release/package/kernel/mt76/patches/0026-wifi-mt76-mt7915-fix-register-mapping.patch

Fixes: cd4c314a65d3 ("mt76: mt7915: refine register definition")
