accel/ivpu: Fix fw log printing

Browse source

commit 4bc988b470 upstream.

  - Fix empty log detection that couldn't work without read_wrap_count
  - Start printing wrapped log from correct position (log_start)
  - Properly handle logs that are wrapped multiple times in reference
    to reader position
  - Don't add a newline when log buffer is wrapped
  - Always add a newline after printing a log buffer in case log does
    not end with one
