Btrfs: Remove the invalid shrink size check up from btrfs_shrink_dev()
Remove an invalid size check up from btrfs_shrink_dev().
The new size should not larger than the device->total_bytes as it was
already verified before coming to here(i.e. new_size < old_size).
Remove invalid check up for btrfs_shrink_dev().
