udf: Fix memory corruption when fs mounted with noadinicb option When UDF filesystem is mounted with noadinicb mount option, it happens that we extend an empty directory with a block. A code in udf_add_entry() didn't count with this possibility and used uninitialized data leading to memory and filesystem corruption. Add a check whether file already has some extents before operating on them. Signed-off-by: Jan Kara <jack@suse.cz>
