Ext[23]: no spare xattr handler slots needed
The ext3_xattr_set_handle2 and ext3_xattr_delete_inode functions contain duplicate code to decrease the reference count of an xattr block. Move this to a separate function.
Also we know we have exclusive access to the inode in ext3_xattr_delete_inode; there is no need to grab the xattr_sem lock.
