Subject[07/20] reiserfs: Fix quota mount option parsing
2.6.32-longterm review patch.  If anyone has any objections, please let me know.

------------------
From: Jan Kara <jack@suse.cz>

commit a06d789b424190e9f59da391681f908486db2554 upstream.

When jqfmt mount option is not specified on remount, we mistakenly clear
s_jquota_fmt value stored in superblock. Fix the problem.
