powerpc: Fix ffi_go_closure_linux64

Browse Source 
Unlike ffi_closure_LINUX64, this entry point is called normally,
so we already have the TOC in R2 and the closure in R11.

	* powerpc/linux64_closure.S (ffi_closure_LINUX64): Remove a
	register dependency chain.
	(ffi_go_closure_linux64): Don't load r11 or r2.
