kernel, fs: Introduce and use set_restart_fn() and arch_set_restart_data()
Preparation for fixing get_nr_restart_syscall() on X86 for COMPAT.
Add a new helper which sets restart_block->fn and calls a dummy
arch_set_restart_data() helper.
Fixes: 609c19a385c8 ("x86/ptrace: Stop setting TS_COMPAT in ptrace code")
