From: Jiang Liu <gerry@xxxxxxxxxxxxxxxxx>
[ Upstream commit a0a455b4bc7483ad60e8b8a50330c1e05bb7bfcf ]
In function psp_init_cap_microcode(), it should bail out when failed to
load firmware, otherwise it may cause invalid memory access.
Fixes: 07dbfc6b102e ("drm/amd: Use `amdgpu_ucode_*` helpers for PSP")
