When cmsOpenProfileFromMem fails, the function returns without calling cmsDeleteContext. Since most random fuzz inputs are not valid ICC profiles, this error path is triggered on the majority of iterations, causing rapid context accumulation in lcms2's global linked list. Fix: add cmsDeleteContext(context) before return on the error path.

Since most random fuzz inputs are not valid ICC profiles,
cmsOpenProfileFromMemfails on the majority of iterations. This makes the context leak high-frequency — contexts accumulate rapidly in lcms2's global linked list.
