[ Upstream commit 78bc3334a69ff289dbc973a9db7c52a2d7757e5b ]
Local variable *reserved* of remove_dquot_ref() is only used if define CONFIG_QUOTA_DEBUG, but not ebraced in CONFIG_QUOTA_DEBUG macro, which leads to unused-but-set-variable warning when compiling.
This patch ebrace it into CONFIG_QUOTA_DEBUG macro like what is done in add_dquot_ref().
