Jonathan Marek fd681a8c7a drm/msm/a6xx: avoid shadow NULL reference in failure path 
commit ce86c239e4 upstream.

If a6xx_hw_init() fails before creating the shadow_bo, the a6xx_pm_suspend
code referencing it will crash. Change the condition to one that avoids
this problem (note: creation of shadow_bo is behind this same condition)

Fixes: e8b0b994c3 ("drm/msm/a6xx: Clear shadow on suspend")
