[PATCH 1/1] gdiplus: add memory cleanup on matrix inversion failure

[Jiajin Cui]

From: Jiajin Cui

Added proper cleanup for allocated memory when matrix inversion fails
in GdipDrawImagePointsRect function. Previously, if GdipInvertMatrix
returned an error status, the function would return immediately without
freeing the src_data buffer that was allocated earlier in the function,
causing a memory leak.

This fix ensures that src_data is properly freed before returning when
matrix inversion fails, preventing memory leaks in error conditions.
