rseq: Always inline rseq_debug_syscall_return() 



To get the full benefit of:

  eaa9088d ("rseq: Use static branch for syscall exit debug when GENERIC_IRQ_ENTRY=y")

clang needs an __always_inline instead of a plain inline qualifier:

	$ for i in {1..10}; do taskset -c 4 perf5 bench syscall basic -l 100000000 | grep "ops/sec"; done

		 Before	     After
	ops/sec  15424491    15872221   +2.9%
