[PATCH] fix the grace time in xfs_quota

[Utako Kusaka <utako@xxxxxxxxxxxxxx>]

Hi,

When a quota limit is reached at a soft limit, xfs_quota(8) shows the 
incorrect grace time.
Because, the subtraction with '__uint32_t' and 'time_t' are done in 
time_to_string(), and the result does not become a negative value, but
a huge value. This patch fixes it.

Example:
xfs_quota> report
User quota on /home/utako/mpnt (/dev/sda6)
                               Blocks
User ID          Used       Soft       Hard    Warn/Grace
---------- --------------------------------------------------
root          3145728       1000       2000     00 [--none--]
utako            1000       1000       2000     00 [00:00:4294967286]  <--

Group quota on /home/utako/mpnt (/dev/sda6)
                               Blocks
Group ID         Used       Soft       Hard    Warn/Grace
---------- --------------------------------------------------
root          3145728          0          0     00 [--------]
users            1000          0          0     00 [--------]
