Subject: btrfs: tests: Fix a memory leak in error handling path in 'run_test()'

From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>


[ Upstream commit 9ca2e97fa3c3216200afe35a3b111ec51cc796d2 ]

If 'btrfs_alloc_path()' fails, we must free the resources already
allocated, as done in the other error handling paths in this function.
