btrfs: fix incorrect error return ret being passed to mapping_set_error
The setting of return code ret should be based on the error code
passed into function end_extent_writepage and not on ret. Thanks
to Liu Bo for spotting this mistake in the original fix I submitted.
Detected by CoverityScan, CID#1414312 ("Logically dead code")
