Subject: [PATCH v2] s390: Remove comment about TIF_FPU

It has been removed in commit 2c6b96762fbd ("s390/fpu: remove TIF_FPU"),
so we should not mention TIF_FPU in the comment here anymore. Since the
remaining parts of the comment just document the obvious fact that
save_user_fpu_regs() saves the FPU state, simply remove the comment now
completely.

 v2: Drop the comment completely
