ftl:remove erase buffer for mtd device without erase interface

Browse source 
When there's no erase function for mtd, we decide if we
need erase_buffer based on this:

1. If we've got bad block marking, we still need the erase buffer.
   If a write fails, it's used to read back the entire bad block's
   contents before writing to a new block.
2. If we don't have bad block marking, the erase buffer isn't
   needed and can be skipped.
