mtd: clean-up the default_mtd_writev function
1. Teach 'mtd_write()' function to return '-EROFS' if the write method
is undefined, and remove the corresponding check from
'default_mtd_writev()'.
2. Do not test 'retlen' for NULL - it cannot be NULL.
3. Few minor coding stile clean-ups.
4. Add a kerneldoc comment
Additionally, minor fixes to the kerneldoc comments of the neighbor function.
