Subject: [PATCH] drm/amdgpu: fix a missing break in a switch statement

From: Colin Ian King <colin.king@...onical.com>

Currently for the AMDGPU_IRQ_STATE_DISABLE there is a missing break
causing the code to fall through to the AMDGPU_IRQ_STATE_ENABLE case.
Fix this by adding in the missing break statement.

Addresses-Coverity: ("Missing break in switch")
Fixes: a644d85a5cd4 ("drm/amdgpu: add gfx v10 implementation (v10)")
