A revert of this CL (patchset #1 id:1) has been created in
https://codereview.chromium.org/1306653005/ by robertocn@chromium.org.

The reason for reverting is: Speculative revert, some builders (Nexus 5, 6 and 9
under chromium.gpu) are failing at the device status check step after this
change due to:

  File "build/android/buildbot/bb_device_status_check.py", line 154, in
blacklisting_device_status
    if not serial in blacklist.Read():
AttributeError: 'NoneType' object has no attribute 'Read'

See
http://build.chromium.org/p/chromium.gpu/builders/Android%20Debug%20%28Nexus%...
for example..

Yeah, this (and that bot not being on recipes) is responsible. Thanks for
reverting.
