LU-6198 test: fix large-lun test_1, test_2 defects

setupall()->start ost called at the end of large-lun.sh
fails to start the ost devices which leads test_1() and
test_2() fail if run separately.

The reasons are:
1) osts data are destroyed by test_1()->llverdev
2) osts are reformatted by test_2, but mds config not changed
Patch fixes the following:
- format Lustre at the end of test_1() and test_2()
- add the "REFORMAT" option check to avoid killing
filesystems that do not want a reformat.
