Subject: [PATCH 3/3] drm/msm: drop redundant debug output

wait_for_completion_timeout returns 0 in case of timeout and never
return < 0 so there is no additional information in printing the
value of time_left here as it will always be 0, thus it can be dropped.

Signed-off-by: Nicholas Mc Guire <hofrat@...dl.org>

This was compile tested with qcom_defconfig +
CONFIG_DRM=m (implies CONFIG_DRM_MSM=m)

Patch is against 4.0-rc7 (localversion-next is -next-20150410)
