rtc: ds1343: clean up ds1343_nvram_read()/ds1343_nvram_write()
The change removes redundant sysfs binary file boundary checks, since this task is already done on caller side in fs/sysfs/file.c Signed-off-by: Vladimir Zapolskiy <vz@mleia.com> Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>
