btrfs: selftests: fix btrfs_test_delayed_refs() leak of transaction
The btrfs_transaction struct leaks, which can cause sporadic fstests
failures when kmemleak checking is enabled:
kmemleak: 5 new suspected memory leaks (see /sys/kernel/debug/kmemleak)
> cat /sys/kernel/debug/kmemleak
unreferenced object 0xffff88810fdc6c00 (size 512):
comm "modprobe", pid 203, jiffies 4294892552

The transaction struct was initially stack-allocated but switched to
heap following frame size compiler warnings.
