Method conduct_neg_test_for_write_caps() in qa/tasks/cephfs/caps_helper.py appends path to command arguments but doesn't delete it after execution. This will lead to 2 paths in second iteration which will lead to a bug in tests.

    def conduct_neg_test_for_write_caps(self, filepaths, mounts):
        cmdargs = ['echo', 'some random data', Raw('|'), 'tee']

        for mount in mounts:
            for path in filepaths:
                if path.find(mount.hostfs_mntpt) != -1:
                    cmdargs.append(path)
                    mount.negtestcmd(args=cmdargs, retval=1,
                                     errmsg='permission denied')

Removing path after the command has bee executed will fix the issue.
