iomap: fix sub-page uptodate handling
commit 1cea335d1db1ce6ab71b3d2f94a807112b738a0f upstream.
bio completions can race when a page spans more than one file system
block. Add a spinlock to synchronize marking the page uptodate.
Fixes: 9dc55f1389f9 ("iomap: add support for sub-pagesize buffered I/O without buffer heads")
