[PATCH v1] regmap: maple: Workaround for another false-positive compiler warning

[Uwe Kleine-König (The Capable Hub)]

Similar to the issue fixed in commit 542440fd7b30 ("regmap: maple: work
around gcc-14.1 false-positive warning"), I see an uninitialized warning
for upper_index and upper_last.

Happens with arc-linux-gnu-gcc (Debian 15.3.0-1) 15.3.0 on an
allmodconfig for ARCH=arc.
