Qingqing Zhuo d7faf6f534 drm/amd/display: Fix system hang after multiple hotplugs (v3)
[Why]
mutex_lock() was introduced in dm_disable_vblank(), which could
be called in an IRQ context. Waiting in IRQ would cause issues
like kernel lockup, etc.

[How]
Handle code that requires mutex lock on a different thread.

v2: squash in compilation fix without CONFIG_DRM_AMD_DC_DCN (Alex)
v3: squash in warning fix (Wei)
