iotests/138: Test leaks/corruptions fixed report

Test that qemu-img check reports the number of leaks and corruptions
fixed in its JSON report (after a successful run).

While touching the _unsupported_imgopts line, adjust the note on why
data_file does not work with this test: The current comment sounds a bit
like it is a mistake for qemu-img check not to check external data
files' refcounts. But there are no such refcounts, so it is no mistake.
Just say that qemu-img check does not do much for external data files,
and this is why this test does not work with them.

qcow2-refcount: avoid eating RAM

an unpredictable amount of memory on corrupted table entries, which are

qcow2-refcount: avoid eating RAM

qcow2_inc_refcounts_imrt() (through realloc_refcount_array()) can eat
an unpredictable amount of memory on corrupted table entries, which are
referencing regions far beyond the end of file.

Prevent this, by skipping such regions from further processing.

Interesting that iotest 138 checks exactly the behavior which we fix
here. So, change the test appropriately.
