[PATCH v3 02/12] xfstests: _scratch_mkfs_sized() for tmpfs

[Junho Ryu <jayr@xxxxxxxxxx>]

From: Hugh Dickins <hughd@xxxxxxxxxx>

_scratch_mkfs_sized() avoid blockdev and update MOUNT_OPTIONS with
required size on tmpfs, so those tests using it can now run.

v3: use -b to check whether SCRATCH_DEV is a block device

v2: check whether SCRATCH_DEV is a block device instead of checking FSTYP
