vfio/spapr_tce: Fix incorrect tce_iommu_group memory free
The @tcegrp variable is used in 1) a loop over attached groups 2) it stores a pointer to a newly allocated tce_iommu_group if 1) found nothing. However the error handler does not distinguish how we got there and incorrectly releases memory for a found+incompatible group. This fixes it by adding another error handling case.
