xfstests fails on nfs4 file system

[Jim Rees <rees@xxxxxxxxx>]

xfstests fails on nfs4 file system:

rhcl1# mount -t nfs -o nfsvers=4,minorversion=1 emc-1:/pnfs2 /mnt/emc-1
rhcl1# cd /home/rees/xfstests
rhcl1# setenv TEST_DEV emc-1:/pnfs2
rhcl1# setenv TEST_DIR /mnt/emc-1/rees/xfstests
rhcl1# ./check -nfs
common.rc: Error: $TEST_DEV (emc-1:/pnfs2) is not a MOUNTED nfs filesystem
/bin/df: `emc-1:/pnfs2': No such file or directory
/bin/df: no file systems processed

Originally nfs4 was a separate file system type, and it still shows up that
way in mtab:
emc-1:/pnfs2/ on /mnt/emc-1 type nfs4 (rw,relatime,vers=4,...

I fixed this by commenting out the type check at the end of common.rc.  I
don't know enough about the innards of xfstests to know what the proper fix
is.  Maybe a substring match, or explicit check for nfs4?
