[PATCH] generic/423: statx mask of the reference file is different from the original file

[Cui Yue <cuiyue-fnst@xxxxxxxxxxxxxx>]

When running xfstests generic/423 to test system call statx() on hard link files of NFS, it fails.
error message:
[!] attr 'stx_mask' differs from ref file, 7ff != e0

The values of parameter "mask" between the original file and the reference file are different.
One is STATX_ALL;
The other is STATX_ATIME | STATX_BTIME | STATX_CTIME | STATX_MTIME.

Modify the function get_reference() to pass the "mask" in,
and change STATX_ATIME | STATX_BTIME | STATX_CTIME | STATX_MTIME to "mask".
