return errno code to caller when error occur, and meanwhile
remove gcc '-Wunused-but-set-variable' warning.

drivers/gpu/drm/amd/amdgpu/../powerplay/smumgr/vegam_smumgr.c: In function vegam_populate_smc_boot_level:
drivers/gpu/drm/amd/amdgpu/../powerplay/smumgr/vegam_smumgr.c:1364:6: warning: variable result set but not used [-Wunused-but-set-variable]
