iomap: fix a regression for partial write errors
When write* wrote some data it should return the amount of written data
and not the error code that caused it to stop. Fix a recent regression
in iomap_file_buffered_write that caused it to return the errno instead.
Fixes: 219580eea1ee ("iomap: update ki_pos in iomap_file_buffered_write")
