printk: ringbuffer: Clarify special lpos values
For empty line records, no data blocks are created. Instead,
these valid records are identified by special logical position
values (in fields of @prb_desc.text_blk_lpos).
Currently the macro NO_LPOS is used for empty line records.
This name is confusing because it does not imply _why_ there is
no data block.
Rename NO_LPOS to EMPTY_LINE_LPOS so that it is clear why there
is no data block.
Also add comments explaining the use of EMPTY_LINE_LPOS as well
as clarification to the values used to represent data-less
blocks.
