mtd: remove retlen zeroing duplication
The MTD API function now zero the 'retlen' parameter before calling the driver's method — do not do this again in drivers. This removes duplicated '*retlen = 0' assignent from the following methods: 'mtd_point()' 'mtd_read()' 'mtd_write()' 'mtd_writev()' 'mtd_panic_write()' Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
