[PATCH] aio: remove bare user-triggerable error printk
The user can generate console output if they cause do_mmap() to fail during sys_io_setup(). This was seen in a regression test that does exactly that by spinning calling mmap() until it gets -ENOMEM before calling io_setup(). We don't need this printk at all, just remove it.
