mtd: block2mtd: fix recursive call of mtd_writev
The 'mtd_writev' interface calls the function assigned to the '_write' field of a given mtd device if that is not NULL. The block2mtd driver sets the '_writev' field to the 'mtd_writev' function itself and thus causes a endless loop. This is caused by 1dbebd32562b3c2caeca35960e5cb00bfcc12900 (mtd: harmonize mtd_writev usage). Remove the assignment from the block2mtd driver to fix the issue.
