Most of the gem_bad_length code is compiled out because creating
a zero-length object is not allowed anymore by i915 and thus it is
not possible to execute it. The remaining part checks that creation of
a zero-length object does indeed fail, which is also checked by
gem_create/create-invalid-size.
The only difference between the 2 tests is that gem_bad_length checks
specifically for EINVAL while create-invalid-size only looks for
failure, so after adding the EINVAL check to create-invalid-size it is
safe to drop gem_bad_length.
