drm/amd: Fix an error handling mistake in psp_sw_init()
[ Upstream commit c01aebeef3ce45f696ffa0a1303cea9b34babb45 ]
If the second call to amdgpu_bo_create_kernel() fails, the memory
allocated from the first call should be cleared. If the third call
fails, the memory from the second call should be cleared.
