misc: force the exact quota options coded into the test

Several tests require setting exactly the quota mount options that are
encoded in the test.  Unfortunately, quota mount options set by the user
in MOUNT_OPTIONS can turn on other quota types, which causes the golden
outputs to be off for various reasons (quota report output, behavior
changes, etc.)

So use _qmount_option to delete all the quota mount options in these
tests so that the test itself can run with exactly the config for which
it was written.
