ide: convert to ->proc_fops
->read_proc, ->write_proc are going away, ->proc_fops should be used instead.
The only tricky place is IDENTIFY handling: if for some reason
taskfile_lib_get_identify() fails, buffer _is_ changed and at least
first byte is overwritten. Emulate old behaviour with returning
that first byte to userspace and reporting length=1 despite overall -E.
