[PATCH 5.4 064/102] drm/amdgpu/vi: silence an uninitialized variable warning

[ Upstream commit 4ff17a1df7d550257972a838220a8af4611c8f2c ]

Smatch complains that we need to initialized "*cap" otherwise it can
lead to an uninitialized variable bug in the caller. This seems like a
reasonable warning and it doesn't hurt to silence it at least.

drivers/gpu/drm/amd/amdgpu/vi.c:767 vi_asic_reset_method() error: uninitialized symbol 'baco_reset'.

Fixes: 425db2553e43 ("drm/amdgpu: expose BACO interfaces to upper level from PP")
