btrfs-progs: adjust the return values for scrub

Browse Source 
o Return 0 to indicate success,
  when detected errors were corrected during scrubbing.
  P.s. This is also to facilitate scripting when return value
       is to be checked.
o Warn the users if there are uncorrectable errors detected.
