m68k: sun3: Fix context restore in flush_tlb_range()

Browse source 
When building with W=1:

    In file included from arch/m68k/kernel/traps.c:42:
    arch/m68k/include/asm/tlbflush.h: In function ‘flush_tlb_range’:
    arch/m68k/include/asm/tlbflush.h:191:28: warning: variable ‘oldctx’ set but not used [-Wunused-but-set-variable]
      191 |         unsigned char seg, oldctx;
	  |                            ^~~~~~

Indeed, the old context is saved, but never restored.  Fix this by
adding the missing call to sun3_put_context().
