[PATCH] drm/amd/display: fix dm irq error message in gpu recover

[Tianci Yin]

From: tiancyin <tianci.yin at amd.com>

[Why]
Variable adev->crtc_irq.num_types was initialized as the value of
adev->mode_info.num_crtc at early_init stage, later at hw_init stage,
the num_crtc changed due to the display pipe harvest on some SKUs,
but the num_types was not updated accordingly, that cause below error
in gpu recover.

  *ERROR* amdgpu_dm_set_crtc_irq_state: crtc is NULL at id :3
  *ERROR* amdgpu_dm_set_crtc_irq_state: crtc is NULL at id :3
  *ERROR* amdgpu_dm_set_crtc_irq_state: crtc is NULL at id :3
  *ERROR* amdgpu_dm_set_pflip_irq_state: crtc is NULL at id :3
  *ERROR* amdgpu_dm_set_pflip_irq_state: crtc is NULL at id :3
  *ERROR* amdgpu_dm_set_pflip_irq_state: crtc is NULL at id :3
  *ERROR* amdgpu_dm_set_pflip_irq_state: crtc is NULL at id :3
  *ERROR* amdgpu_dm_set_vupdate_irq_state: crtc is NULL at id :3
  *ERROR* amdgpu_dm_set_vupdate_irq_state: crtc is NULL at id :3
  *ERROR* amdgpu_dm_set_vupdate_irq_state: crtc is NULL at id :3

[How]
Defer the initialization of num_types to eliminate the error logs.
