udf: Return -ENOMEM when allocation fails in udf_get_filename()

Browse source

Return -ENOMEM when allocation fails in udf_get_filename(). Update
udf_pc_to_char(), udf_readdir(), and udf_find_entry() to handle the
error appropriately. This allows us to pass appropriate error to
userspace instead of corrupting symlink contents by omitting some path
elements.
