rseq: Always inline rseq_debug_syscall_return()
To get the full benefit of:
eaa9088d568c ("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%
