Fix filesystem resize by calling e2fsck -f
first
Previously when the block device was resized the partition table was also resized but the filesystem was not. For an increase from 64GiB to 128GiB the console showed: * Configuring host block device .../dev/vda1: clean, 62/4194304 files, 604445/16776960 blocks Resizing disk partition: Unpartitioned space /dev/vda: 64 GiB, 68719476736 bytes, 134217728 sectors resize2fs 1.43.3 (04-Sep-2016) Please run 'e2fsck -f /dev/vda1' first. /dev/vda1: clean, 62/4194304 files, 604445/16776960 blocks This patch makes `resize2fs` happy by running `e2fsck -f` beforehand as requested.
