kernel/ksysfs.c: add __ro_after_init to bin_attribute structure
The object notes_attr of type bin_attribute is not modified after getting initailized by ksysfs_init. Apart from initialization in ksysfs_init it is also passed as an argument to the function sysfs_create_bin_file but this argument is of type const. Therefore, add __ro_after_init to its declaration.
