Zhihao Cheng a5f643ab11 ubi: Refuse attaching if mtd's erasesize is 0 ...

[ Upstream commit 017c73a34a661a861712f7cc1393a123e5b2208c ]

There exists mtd devices with zero erasesize, which will trigger a
divide-by-zero exception while attaching ubi device.
Fix it by refusing attaching if mtd's erasesize is 0.
