drm/amdgpu: bail out when failed to load fw in psp_init_cap_microcode() 

[ 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: 07dbfc6b10 ("drm/amd: Use `amdgpu_ucode_*` helpers for PSP")
