[RFC PATCH 08/17] dyndbg: reduce verbose/debug clutter

[Jim Cromie]

currently, for verbose=3, this is logged:

[ 3832.333424] dyndbg: parsed: func="" file="" module="amdgpu" format="" lineno=0-0 class=DRM_UT_PRIME
[ 3832.333888] dyndbg: no matches for query
[ 3832.334093] dyndbg: no-match: func="" file="" module="amdgpu" format="" lineno=0-0 class=DRM_UT_PRIME
[ 3832.334570] dyndbg: processed 1 queries, with 0 matches, 0 errs

This patch removes 2nd & 3rd lines;
 3 differs from 1 only by status
 2 is just status, retold in 4, with more info.
