mtd: lart: initialize writebufsize
The writebufsize concept was introduce by commit "0e4ca7e mtd: add writebufsize field to mtd_info struct" and it represents the maximum amount of data the device writes to the media at a time. This is an important parameter for UBIFS which is used during recovery and which basically defines how big a corruption caused by a power cut can be. Set writebufsize to 4 because this drivers writes at max 4 bytes at a time.
