3.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Vyacheslav Dubeyko <slava@xxxxxxxxxxx>
commit 2df37a19c686c2d7c4e9b4ce1505b5141e3e5552 upstream.
Remove double call of bio_put() in nilfs_end_bio_write() for the case of
BIO_EOPNOTSUPP error detection. The issue was found by Dan Carpenter
and he suggests first version of the fix too.
