Pointer bdev is being initialized however this value is never
read as bdev is assigned an updated value from the returned
call to blkdev_get_by_path. Remove the redundant assignment.
Cleans up clang warning:
drivers/mtd/devices/block2mtd.c:228:23: warning: Value stored to
'bdev' during its initialization is never read
