[PATCH 19/40] sim/m32r: Initialize "list" variable

[Tsukasa OI]

The variable "list" is only initialized when arg1 > 0 and when arg1 == 0,
an uninitialized value is passed to translate_endian_h2t function.

Although this behavior is harmless, this commit adds initialization to avoid
a GCC warning ("-Wmaybe-uninitialized").
