[REG2.064a] Issue 11105 - Error on struct with multidimentional static array initialization from its element

http://d.puremagic.com/issues/show_bug.cgi?id=11105

Sorry my [wrong refactoring](https://github.com/D-Programming-Language/dmd/commit/c4ee0c1ef6a3d98227a2eab7c43a6b48ba48ce01#diff-31ec3d6838ade0264adec0944948507dL4680) had caused the bug.
Just revert the code.
