x86: Move TS_COMPAT back to asm/thread_info.h
Move TS_COMPAT back to asm/thread_info.h, close to TS_I386_REGS_POKED.
It was moved to asm/processor.h by b9d989c7218a ("x86/asm: Move the thread_info::status field to thread_struct"), then later 37a8f7c38339 ("x86/asm: Move 'status' from thread_struct to thread_info") moved the 'status' field back but TS_COMPAT was forgotten.
Preparatory patch to fix the COMPAT case for get_nr_restart_syscall()
