block: Don't invalidate pagecache for invalid falloc modes
commit 1364a3c391aedfeb32aa025303ead3d7c91cdf9d upstream.
Only call truncate_bdev_range() if the fallocate mode is supported. This
fixes a bug where data in the pagecache could be invalidated if the
fallocate() was called on the block device with an invalid mode.
Fixes: 25f4c41415e5 ("block: implement (some of) fallocate for block devices")
