powerpc: Remove the redundant flush_fp_to_thread() in setup_sigcontext()
In commit c6e6771b(powerpc: Introduce VSX thread_struct and CONFIG_VSX) we add a invocation of flush_fp_to_thread() before copying the FPR or VSR to users. But we already invoke the flush_fp_to_thread() in this function. So remove one of them. Signed-off-by: Kevin Hao <haokexin@gmail.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
