It looks like the problem is that reiserfs_new_inode can be called either having xattrs locked or not.
It does unlocking/locking xattrs on error handling path, but has no idea about whether
xattrs are locked of not.
The attached patch seems to fix the problem.
I am not sure whether it is correct way to fix this problem, though.

Tarmo, please check if this patch works for you.
