currently, for verbose=3, these are logged for each query

 dyndbg: query 0: <class DRM_UT_CORE +p> mod: <*>
 dyndbg: split into words: "class" "DRM_UT_CORE" "+p"
 dyndbg: op='+'
 dyndbg: flags=0x1
 dyndbg: *flagsp=0x1 *maskp=0xffffffff
 dyndbg: parsed: func="" file="" module="" format="" lineno=0-0 class=...
 dyndbg: no matches for query
 dyndbg: no-match: func="" file="" module="" format="" lineno=0-0 class=...
 dyndbg: processed 1 queries, with 0 matches, 0 errs

That is excessive, so this patch shrinks it to 4 lines:

 dyndbg: query 0: <class D2_CORE +T:foo > on module: <*>
 dyndbg: split into words: "class" "D2_CORE" "+T:foo"
 dyndbg: op='+' flags=0x40 maskp=0xffffffff trace_dest=0x0
 dyndbg: applied: func="" file="" module="" format="" lineno=0-0 class=...
