    Description

      In llog_cat_new_log() we create a spurious memory leak warning when we use OBD_FREE_PTR(loghandle->lgh_hdr) rather than OBD_FREE(..., loghandle->lgh_ctxt->loc_chunk_size).

      From leak_finder.pl:

      *** Free different size (32768 alloced, 8192 freed).
    malloc at llog.c:llog_init_handle:345, free at llog_cat.c:llog_cat_new_log:104
