LU-4340 tests: Fix test_69 of conf-sanity test

Since 100% inodes were used with default value of MDSSIZE and OSTSIZE,
test_69 of conf-sanity test was failing with ENOSPC error.

Use decreased value of num_create to create 20000*3 files.

Also added umount of client before OST replace operation so that
eviction/recovery of client is not seen.
