[PATCH] xfs_repair: always print an estimate when reporting progress

[Donald Douwsma <ddouwsma@redhat.com>]

If xfs_repair completes the work for a given phase while allocation
groups are still being processed the estimated time may be zero, when
this occures xfs_repair prints an incomplete string.

 # xfs_repair -o ag_stride=4 -t 1 /dev/sdc

         - agno = 0
         - 20:52:13: process known inodes and inode discovery - 3456 of 40448 inodes done
         - 20:52:14: process known inodes and inode discovery - 3456 of 40448 inodes done
         - 20:52:14: Phase 3: elapsed time 1 second - processed 207360 inodes per minute
         - 20:52:14: Phase 3: 8% done - estimated remaining time 10 seconds
         - 20:52:15: process known inodes and inode discovery - 3456 of 40448 inodes done
         - 20:52:15: Phase 3: elapsed time 2 seconds - processed 103680 inodes per minute
         - 20:52:15: Phase 3: 8% done - estimated remaining time 21 seconds
         - 20:52:16: process known inodes and inode discovery - 33088 of 40448 inodes done
         - 20:52:16: Phase 3: elapsed time 3 seconds - processed 661760 inodes per minute
         - 20:52:16: Phase 3: 81% done - estimated remaining time
         - agno = 1
 	...

Make this more consistent by printing 'estimated remaining time 0
seconds' if there is a 0 estimate.
