drm/amdgpu: fix regresstion on SR-IOV gpu reset failed

fw ucode is corrupted after vf flr by PSP so ucode_init() is
a must in psp_hw_init othewise KIQ/KCQ enabling will fail

Revert "drm/amdgpu: refine code delete duplicated error handling"
This reverts commit e57b87ff828f95efe992468e6d18c2c059b27aa9.
Revert "drm/amdgpu: move amdgpu_ucode_init_bo to amdgpu_device.c"
This reverts commit 815b8f8595148d06a64d2ce4282e8e80dfcb02f1.
