[PATCH v2 09/10] hw/intc: Remove redundant statement in exynos4210_combiner_read()

[Chen Qun]

Clang static code analyzer show warning:
hw/intc/exynos4210_combiner.c:231:9: warning: Value stored to 'val' is never 
read
        val = s->reg_set[offset >> 2];

The default value of 'val' is '0', so we can break the 'default' branch and 
return 'val'.
