btrfs: return error pointer from alloc_test_extent_buffer
[ Upstream commit b6293c821ea8fa2a631a2112cd86cd435effeb8b ]
Callers of alloc_test_extent_buffer have not correctly interpreted the
return value as error pointer, as alloc_test_extent_buffer should behave
as alloc_extent_buffer. The self-tests were unaffected but
btrfs_find_create_tree_block could call both functions and that would
cause problems up in the call chain.
Fixes: faa2dbf004e8 ("Btrfs: add sanity tests for new qgroup accounting code")
