drm/amd/display: Avoid get/put vblank when stream disabled
[Why]
amdgpu_dm_crtc_set_crc_source() will call
amdgpu_dm_crtc_configure_crc_source() to enable/disable CRC
generation. However, configuration will be deferred to stream enabled.
If stream is not enabled, current flow will still try to get/put vblank
refcount.
[How]
Return EINVAL to skip actions on vblank refcount when stream is not
enabled.
