In preparation for moving arm64 over to the generic entry code, rename syscall_trace_exit() to syscall_exit_work(). The renamed function checks and prevents illegal system calls inside user-space rseq critical sections, while also handling tracing, auditing, and ptrace reporting. No functional changes.
