The function btrfs_abort_transaction() only accepts negative error code,
and have the macro VERIFY_NEGATIVE_ERROR() to verify that error code.
But inside update_raid_extent_item(), if there is such key found, we
return 1, breaking the negative error code scheme.
Furthermore if we hit some real error during the tree search, e.g. -EIO,
then the error code is always over-written to -EINVAL.
Fix both problems by following other call sites by overwriting @ret to
-ENOENT if the btrfs_search_slot() failed to locate the key.
This is very unlikely to hit, as we only enter update_raid_extent_item()
if there is a conflicting key already in the raid stripe tree.
This was reported by Sashiko when reviewing another patch.
