color-device: Don't close lcms profile on error from cd_icc_load_handle

As implemented in colord 1.4.6, cd_icc_load_handle() has three possible
results:

1. success, taking ownership of the profile;
2. failure because cmsGetProfileContextID returns NULL, *not* taking
   ownership of the profile;
3. failure in cd_icc_load(), taking ownership of the profile.

The previous commit ensures that we are not in case 2.

In case 3 where cd_icc_load() fails, ownership was already given to
the colord CdIcc object, so it will be freed when the g_autoptr unrefs
the CdIcc, and we must not free it again: that would be a double-free,
potentially resulting in memory corruption.
