x86, compat: Use test_thread_flag(TIF_IA32) in compat signal delivery
commit 0b91f45b23cb73ce11acdc3cf4c6efd4441e3b3e upstream.
Signal delivery compat path may not have the 'TS_COMPAT' flag (that
flag indicates how we entered the kernel). So use
test_thread_flag(TIF_IA32) instead of is_ia32_task(): one of the
functions of TIF_IA32 is just what kind of signal frame we want.
