[PATCH 2/2] Don't run tests that require block devices for virtual filesystems

[Jan Kara <jack@suse.cz>]

Some tests require block device based filesystems (e.g. because they
setup dm device in a particular way). These tests then fail for tmpfs in
unusual ways (usually trying to call mkfs.tmpfs). Annotate these tests
as requiring block device based filesystem so that we gracefully exit
with _notrun. Also there's no point in simulating successful _mkfs_dev
for such filesystems since the test is unlikely to test anything
sensible. So delete that workaround from _mkfs_dev.
