ext4: Change remaining tracepoints to use folio
ext4_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)
As a minor bit of optimization to avoid an extra dereferencing,
since both of the above functions already were dereferencing
folio->mapping->host, hence change the tracepoint argument to take
(inode, folio).
