[LTP] [PATCH 4/4] syscalls/quotactl02.c: Add Q_XGETQSTATV test

[Yang Xu]

This cmd returns XFS filesystem-specific quota information in the fs_quota_statv
pointed to by addr. The qs_version field of the structure should be filled with
the version of the structure supported by the caller (for now, only FS_QSTAT_VERSION1
is supported).
