drm/i915/selftest: Fix use of err in igt_reset_{fail, nop}_engine()
Clang warns:
In file included from drivers/gpu/drm/i915/gt/intel_reset.c:1514:
drivers/gpu/drm/i915/gt/selftest_hangcheck.c:465:62: warning: variable
'err' is uninitialized when used here [-Wuninitialized]
pr_err("[%s] Create context failed: %d!\n", engine->name, err);

2 warnings generated.
This appears to be a copy and paste issue. Use ce directly using the %pe
specifier to pretty print the error code so that err is not used
uninitialized in these functions.
