m68k: sun3: Fix context restore in flush_tlb_range()
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().
