Bug in UDF, setting larger file size when data in ICB

in fs/udf/inode.c, udf_setsize(), if the new size is larger than the old
size and the old data is in the ICB and the new size still fits in the
ICB (iinfo->i_alloc_type == ICBTAG_FLAG_AD_IN_ICB and iinfo->i_lenAlloc
= newsize), udf_extend_file() is called which promptly calls BUG()
because it does not like this i_alloc_type value.
I think the simplest fix would be to add a 'goto' after the assignment
to iinfo->i_lenAlloc, bypassing the call to udf_extend_file().
