http: remove adapter frame from onParserExecute

Remove a pointless adapter frame  by fixing up the function's formal
parameter count.  Before:

    frame #0: 0x000033257ea446d5 onParserExecute(...)
    frame #1: 0x000033257ea3b93f <adaptor>
    frame #2: 0x000033257ea41959 <internal>
    frame #3: 0x000033257e9840ff <entry>

After:

    frame #0: 0x00000956287446d5 onParserExecute(...)
    frame #1: 0x0000095628741959 <internal>
    frame #2: 0x00000956286840ff <entry>
