Max Filippov a1a6f8a14c xtensa: fix system_call interaction with ptrace ...

[ Upstream commit 02ce94c229251555ac726ecfebe3458ef5905fa9 ]

Don't overwrite return value if system call was cancelled at entry by
ptrace. Return status code from do_syscall_trace_enter so that
pt_regs::syscall doesn't need to be changed to skip syscall.
