[PATCH] iommu/amd: Propagate the error code returned by __modify_irte_ga() in modify_irte_ga()
The return type of __modify_irte_ga() is int, but modify_irte_ga() treats it as a bool. Casting the int to bool discards the error code.
To fix the issue, change the type of ret to int in modify_irte_ga().
