":-xfs" means assign the value of $xfs if $FTYPE is null. xfs is not
a variable....

If the default value expansion is fixed, FSTYP will always have a
value here Hence it will never, ever probe.

I suspect what you want is:
-FSTYP=xfs
.....
if [ -z "$FSTYP" -a "$HOSTOS" == "Linux" ]; then
FSTYP=`blkid -c /dev/null -s TYPE -o value $TEST_DEV`
fi
FSTYP=${FSTYP:=xfs}
export FSTYP
