[PATCH] xfs/259: disable CRC if testing with 512 bytes block size

[Eryu Guan <eguan@xxxxxxxxxx>]

With CRCs being the default, TEST_DEV can still be created with
"-m crc=0" option explicitly, then 512 bytes block size is picked up by
the test, which causes mkfs failure in later mkfs tests.

Fix it by adding "-m crc=0" mkfs option in this case.
