Dave Martin bd7d069c76 ARM: 8643/3: arm/ptrace: Preserve previous registers for short regset write ...

commit 228dbbfb5d upstream.

Ensure that if userspace supplies insufficient data to
PTRACE_SETREGSET to fill all the registers, the thread's old
registers are preserved.

Fixes: 5be6f62b00 ("ARM: 6883/1: ptrace: Migrate to regsets framework")
