tst_test.sh: Fix check for non-mounted device
1) unset TST_DEVICE if acquiring failed
2) do not try to umount the device in this case
Maybe sometimes missing $device in tst_umount()
is error, but mostly at least in case of df01.sh
it's not, therefore return without warning.
This fixes error:
df01 1 TBROK: Failed to acquire device
grep: Unmatched [, [^, [:, [., or [=
grep: Unmatched [, [^, [:, [., or [=
df01 1 TINFO: The tst_device 0 TINFO : Found free device 0 '/dev/loop0'
Test device='/dev/loop0'
tst_device 0 TINFO : Formatting /dev/loop0 with ext2 opts='' extra opts='' is not mounted, skipping umount
Fixes: 5c846a0f6 shell: Add $TST_DEVICE as default parameter to tst_umount
