Error injection testing uncovered a case where we ended up with invalid
link counts on an inode.  This happened because we failed to notice an
error when updating the inode while replaying the tree log, and
committed the transaction with an invalid file system.  Fix this by
checking the return value of btrfs_update_inode.  This resolved the link
count errors I was seeing, and we already properly handle passing up the
error values in these paths.
