mtd: sst25l: initialize writebufsize
commit c4cc625ea5958d065c21cc0fcea29e9ed8f3d2bc upstream. 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 the flash page size because it is the maximum amount of data it writes at a time.
