printk_ringbuffer: Add sanity check for 0-size data
get_data() has a sanity check for regular data blocks to ensure at
least space for the ID exists. But a regular block should also have
at least 1 byte of data (otherwise it would be data-less instead of
regular).
Expand the get_data() block size sanity check to additionally expect
at least 1 byte of data.
