Subject: [RFCv1 2/4] ext4: Change remaining tracepoints to use folio

est4_readpage() is converted to ext4_read_folio() hence change the
related tracepoint from trace_ext4_readpage(page) to
trace_ext4_read_folio(folio).

Do the same for trace_ext4_releasepage(page) to
trace_ext4_release_folio(folio)
