Subject: [RFCv1 1/4] ext4: kill unused function ext4_journalled_write_inline_data

Commit 3f079114bf522 ("ext4: Convert data=journal writeback to use ext4_writepages()")
Added support for writeback of journalled data into ext4_writepages()
and killed function __ext4_journalled_writepage() which used to call
ext4_journalled_write_inline_data() for inline data.
This function got left over by mistake. Hence kill it's definition as
no one uses it.
