Nicholas Kazlauskas e39575b9c3 drm/amd/display: Fix CRC vblank refs when changing interrupts
[Why]
We only currently drop the vblank reference when the stream is
being removed from the context. We should be dropping it whenever we
disable interrupts and reaquiring it after we re-enable them.

We also never get the extra reference correctly when re-enabling
interrupts, since grabbing the reference has the following condition:

if (!crtc_state->crc_enabled && enable)
        drm_crtc_vblank_get(crtc);

This means that crc_enabled must be *false* in order to grab the extra
reference.

[How]
Always drop the ref whenever we're disabling interrupts.

Only disable CRC capture when the stream is being removed.

Always grab the ref by setting dm_new_crtc_state->crc_enabled = false
before the call to re-enable CRC capture.
