[PATCH] io_uring/waitid: remove #ifdef CONFIG_COMPAT

[Caleb Sander Mateos <csander@purestorage.com>]

io_is_compat() is already defined to return false if CONFIG_COMPAT is
disabled. So remove the additional #ifdef CONFIG_COMPAT guards. Let the
compiler optimize out the dead code when CONFIG_COMPAT is disabled.
