Summary
btrfs: fix ulist leaks in error paths of qgroup self tests
Details

In the Linux kernel, the following vulnerability has been resolved:

btrfs: fix ulist leaks in error paths of qgroup self tests

In the testnosharedqgroup() and testmultiplerefs() qgroup self tests, if we fail to add the tree ref, remove the extent item or remove the extent ref, we are returning from the test function without freeing the "oldroots" ulist that was allocated by the previous calls to btrfsfindallroots(). Fix that by calling ulistfree() before returning.
