From: Damien Le Moal <damien.lemoal@opensource.wdc.com>

commit 23ef63d5e14f916c5bba39128ebef395859d7c0f upstream.

If ata_read_log_page() fails to read a log page, the ata_dev_err() error
message only print the page number, omitting the log number. In case of
error, facilitate debugging by also printing the log number.
