[ Upstream commit 9fabbdf338b701f2d763d9edbc3e82ce1e7fa1b4 ]
The test_cmd_destroy_access() should end with a semicolon, so add one.
There is a test_ioctl_destroy(ioas_id) following already, so drop one.

iommufd: Add a selftest2022-12-01T00:16:49ZJason Gunthorpejgg@nvidia.com2022-11-29T20:29:42Zurn:sha1:57f0988706fec1b8dbc3fe00965828a47e2235a1
Cover the essential functionality of the iommufd with a directed test from
userspace. This aims to achieve reasonable functional coverage using the
in-kernel self test framework.
A second test does a failure injection sweep of the success paths to study
error unwind behaviors.
This allows achieving high coverage of the corner cases in pages.c.
The selftest requires CONFIG_IOMMUFD_TEST to be enabled, and several huge
pages which may require:
echo 4 > /proc/sys/vm/nr_hugepages
