block-migration: fix blk_mig_save_dirty_block() return value checking
Commit 43be3a25c931a7f61a76fbfc9d35584cbfc5fb58 changed the
blk_mig_save_dirty_block() return code handling. The function's doc
comment says:
/* return value:
* 0: too much data for max_downtime
* 1: few enough data for max_downtime
*/
Because of the 1 return value, callers must check for ret < 0 instead of
just:
if (ret) { ... }
We do not want to bail when 1 is returned, only on error.
