wifi: rtl8xxxu: tighten bounds checking in rtl8xxxu_read_efuse()
[ Upstream commit 620d5ea ] There some bounds checking to ensure that "map_addr" is not out of bounds before the start of the loop. But the checking needs to be done as we iterate through the loop because "map_addr" gets larger as we iterate.
