Log: zio: align use of "no dump" flag between use_uma and !use_uma cases At the moment no ZFS buffers are included into a crash dump unless ZFS_DEBUG (or INVARIANTS) kernel option is enabled. That's not very helpful for debugging of ZFS problems, because important information often resides in metadata buffers. This change switches the dumping behavior when UMA is used from the illumos behavior to a more useful behavior that we have on FreeBSD when ZFS buffers are allocated via malloc.
