parisc: Fix ptrace check on syscall return
commit 8779e05ba8aaffec1829872ef9774a71f44f6580 upstream. The TIF_XXX flags are stored in the flags field in the thread_info struct (TI_FLAGS), not in the flags field of the task_struct structure (TASK_FLAGS). It seems this bug didn't generate any important side-effects, otherwise it wouldn't have went unnoticed for 12 years (since v2.6.32).
