Konstantin Belousov b1e2f063ae amd64 sendsig: fix context corruption
Drop fpstate only after copying out xfpustate from the thread usermode
save area. Otherwise a context switch between get_fpcontext(), which now
returns the pointer directly into user save area, and copyout, would
cause reinit of the save area, loosing user registers.
