dmesg info after running module_reload

System Environment:
--------------------------
Platform:        Ivybridge
Kernel: (drm-intel-nightly)2fc764a311ca1e51c69ac3ff2872ae49617f9b46
Bug detailed description:
-------------------------
   On IVB platform with a  NVDIA video card ,while running module_reload it shows:
ERROR: Module drm_kms_helper is in use by nouveau
ERROR: Module drm is in use by nouveau,ttm,drm_kms_helper
module successfully unloaded
module successfully loaded again
   Does this show correctly? The  NVDIA video card shouldn't effect this cause.
   BTW:The case prime_nv_api can run correctly.

It didn't fail as such, just the test case is a little noisy.

    tests/module_reload: Silence warnings when unloaded shared modules
    
    So long as we spit out critical errors during i915 reload, or detect any
    oops the test will do its job.
