drm/amdgpu: fix dm_suspend/resume arguments to ip_block

"build failure after merge of the amdgpu tree"
dm_suspend/dm_resume functions argument mismatch
not caught in validation as it was under config
CONFIG_DEBUG_KERNEL_DC which wasnt enabled by
default.

Change argument from adev to ip_block.

Fixes: 982d7f9bfe4a ("drm/amdgpu: update the handle ptr in suspend")
Fixes: 7feb4f3ad8be ("drm/amdgpu: update the handle ptr in resume")
