pnfs/blocklayout: Fix device leaks on parse failure
bl_parse_concat() and bl_parse_stripe() allocate a child device array and
then parse each child in turn. If parsing a child fails, the failed child is
not counted in nr_children and the parent may be left with a children array
that bl_free_device() will not release when nr_children is zero.
Release the failed child and the already parsed children before returning the
error. Also make bl_free_device() release the child array whenever the
children pointer is set, so that partially initialised concat or stripe
devices are cleaned up correctly.
bl_parse_scsi() can also fail after assigning d->bdev_file and dropping the
file reference. Clear the pointer after fput() so that an outer cleanup path
does not put it again.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
