[0/3] udf: Fix handling of in-ICB files

Hello,

conversion of UDF to use the same address_space operations for normal an inline
(in-ICB) files had two bugs resulting in buffered reads / writes not really
working properly for in-ICB files. Interestingly none of the xfstests
discovered this (likely because files have to be small to fit within ICB and
you have to evict the first file page from the page cache to notice). I've
now verified with manual testing that read & writes to in-ICB files work
again after these fixes. I plan to push these fixes to Linus through my
tree soon.
