x86/ia32_signal: Propagate __user annotation properly
Commit
57d563c82925 ("x86: ia32_setup_rt_frame(): consolidate uaccess areas")
dropped a __user annotation in a cast when refactoring __put_user() to
unsafe_put_user().
Hence, since then, sparse warns in arch/x86/ia32/ia32_signal.c:350:9:
warning: cast removes address space '__user' of expression
warning: incorrect type in argument 1 (different address spaces)
expected void const volatile [noderef] __user *ptr
got unsigned long long [usertype] *
Add the __user annotation to restore the propagation of address spaces.
