ext4: Make ext4_write_inline_data_end() use folio

Browse source 
ext4_write_inline_data_end() is completely converted to work with folio.
Also all callers of ext4_write_inline_data_end() already works on folio
except ext4_da_write_end(). Mostly for consistency and saving few
instructions maybe, this patch just converts ext4_da_write_end() to work
with folio which makes the last caller of ext4_write_inline_data_end()
also converted to work with folio.
We then make ext4_write_inline_data_end() take folio instead of page.
