ext4: fix warning in ext4_handle_inode_extension

Above issue may happen as follows: Assume inode.i_size=4096 EXT4_I(inode)->i_disksize=4096

step 1: set inode->i_isize = 8192 ext4_setattr if (attr->ia_size != inode->i_size) EXT4_I(inode)->i_disksize = attr->ia_size; rc = ext4_mark_inode_dirty ext4_reserve_inode_write ext4_get_inode_loc __ext4_get_inode_loc sb_getblk --> return -ENOMEM ... if (!error) ->will not update i_size i_size_write(inode, attr->ia_size); Now: inode.i_size=4096 EXT4_I(inode)->i_disksize=8192

step 2: Direct write 4096 bytes ext4_file_write_iter ext4_dio_write_iter iomap_dio_rw ->return error if (extend) ext4_handle_inode_extension WARN_ON_ONCE(i_size_read(inode) < EXT4_I(inode)->i_disksize); ->Then trigger warning.

To solve above issue, if mark inode dirty failed in ext4_setattr just set 'EXT4_I(inode)->i_disksize' with old value.
