[PATCH] xfstests: restrict 259 device sizes to multiples of 512

[Eric Sandeen]

Test 259 tries to make a loop device size which is 1 byte less
than 4T; losetup now warns that this makes little sense, and
the warning breaks the test output:

    +losetup: /mnt/test/259.image: warning: file does not fit into a 512-byte sector the end of the file will be ignored.

The RH QE testcase did originally use loopback, so
did not test anything other than 512 boundaries.

Just drop the 1-byte-shy case, because it produces a device
exactly the same size as the 512-bytes-shy case.

(FWIW, this is a regression test for the bug that
d943b11 mkfs: get size of device properly
fixed.)
