iomap: iomap_write_end cleanup

Browse Source 
In iomap_write_end(), only call iomap_write_failed() on the byte range
that has failed.  This should improve code readability, but doesn't fix
an actual bug because iomap_write_failed() is called after updating the
file size here and it only affects the memory beyond the end of the
file.
