udf: Move handling of uniqueID into a helper function and protect it by a s_alloc_mutex
uniqueID handling has been duplicated in three places. Move it into a common helper. Since we modify an LVID buffer with uniqueID update, we take sbi->s_alloc_mutex to protect agaist other modifications of the structure. Signed-off-by: Jan Kara <jack@suse.cz>
