Subject: [PATCH] ring-buffer: fix kernel-doc format to avoid a warning

Format the kernel-doc for RINGBUF_TYPE_DATA_TYPE_LEN_MAX correctly
to prevent a kernel-doc warning:

Warning: include/linux/ring_buffer.h:61 Enum value
 'RINGBUF_TYPE_DATA_TYPE_LEN_MAX' not described in enum 'ring_buffer_type'

Fixes: 334d4169a659 ("ring_buffer: compressed event header")
