That's a fun way of doing "itoa()" :)
How about using helpers? We have igt_sysfs_set_parameter.
Other thing is the fact that we're leaving the machine in a non-default state
(global reset rather than per-engine reset).
We should actually restore the old value after the test.
I can also see that's "by design" (hang detector), but if we change the
behaviour of hang detector in the future, we may forget to modify gem_eio.
