Subject: [PATCH] anon_inodes: remove redundant file->f_mapping initialization

In anon_inode_getfile(), file->f_mapping is redundantly initialized to
anon_inode_inode->i_mapping, since it has already been initialized in
alloc_file_pseudo() -> alloc_file(), so remove the initialization in
anon_inode_getfile().
