powerpc/ptrace: Preserve previous fprs/vsrs on short regset write
commit 99dfe80a2a246c600440a815741fd2e74a8b4977 upstream.
Ensure that if userspace supplies insufficient data to PTRACE_SETREGSET
to fill all the registers, the thread's old registers are preserved.
Fixes: c6e6771b87d4 ("powerpc: Introduce VSX thread_struct and CONFIG_VSX")
