Subject: [PATCH v2 5/6] xfs/015: check _scratch_mkfs_sized return code

The test cases xfs/015 calls _scratch_mkfs before _scratch_mkfs_sized,
and does not check return code of _scratch_mkfs_sized. Even if
_scratch_mkfs_sized failed, _scratch_mount after it cannot detect the
sized mkfs failure because _scratch_mkfs already created a file system
on the device. This results in unexpected test condition.

To avoid the unexpected test condition, check return code of
_scratch_mkfs_sized.
