UBIFS: Add an assertion for clean_zn_cnt
This patch adds a new ubifs_assert() in ubifs_tnc_close() to check
if there are any leaks of per-filesystem @clean_zn_cnt. This new
assert inspects whether the return value of ubifs_destroy_tnc_subtree()
is equal to @clean_zn_cnt or not while umount.
Artem: a minor amendment
