UBIFS: xattr bugfixes
Xattr code has not been tested for a while and there were serveral bugs. One of them is using wrong inode in 'ubifs_jnl_change_xattr()'. The other is a deadlock in 'ubifs_setxattr()': the i_mutex is locked in 'cap_inode_need_killpriv()' path, so deadlock happens when 'ubifs_setxattr()' tries to lock it again. Thanks to Zoltan Sogor for finding these bugs. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
