[PATCH] xfs_quota: display default limits for users with zero usage

[Ravi Singh <ravising@redhat.com>]

When the kernel returns default quota limits for IDs without a dquot
on disk, xfs_quota suppresses the output because it only checks
usage counters (d_bcount, d_icount, d_rtbcount). If all counters
are zero the line is skipped even though non-zero limits apply.

Also check the soft/hard limit fields so that quota output is
displayed whenever limits are configured, even if usage is zero.

This is the userspace companion to the kernel commit:
"xfs: return default quota limits for IDs without a dquot"
