drm/amd/pm: fix indenting in __smu_cmn_reg_print_error()

Smatch complains that the dev_err_ratelimited() is indented one tab more
than the surrounding lines.

	drivers/gpu/drm/amd/amdgpu/../pm/swsmu/smu_cmn.c:174
	__smu_cmn_reg_print_error() warn: inconsistent indenting

It looks like it's not a bug, just that the indenting needs to be cleaned
up.
