sparc64: Fix bug in PTRACE_SETFPREGS64 handling.

[ Upstream commit 5769907ade8dda7002b304c03ef9e4ee5c1e0821 ]

From: Chris Torek <chris.torek@windriver.com>

>The SPARC64 kernel code for PTRACE_SETFPREGS64 appears to be an exact copy
>of that for PTRACE_GETFPREGS64.  This means that gdbserver and native
>64-bit GDB cannot set floating-point registers.

It looks like a simple typo.
