iova: Remove some magazine pointer NULL checks
Since commit 32e92d9f ("iommu/iova: Separate out rcache init") it has not been possible to have NULL CPU rcache "loaded" or "prev" magazine pointers once the IOVA domain has been properly initialized. Previously it was only possible to have NULL pointers from failure to allocate the magazines in the IOVA domain initialization. The only other two functions to modify these pointers - __iova_rcache_{get, insert}() - would already ensure that these pointers were non-NULL if initially non-NULL. As such, the mag NULL pointer checks in iova_magazine_full(), iova_magazine_empty(), and iova_magazine_free_pfns() may be dropped. Signed-off-by:John Garry <john.garry@huawei.com> Reviewed-by:
