Subject: [PATCH] ext4/059: disable block_validity checks when mounting a corrupted file system

Kernels with the commit "ext4: add correct group descriptors and
reserved GDT blocks to system zone" will refuse to mount the corrupted
file system constructed by this test.  So in order to perform the
test, we need to disable the block_validity checks.
