oxnas: sata_oxnas: use ata_link_err

Kernel 5.15.86 has backported ("ata: libata: move ata_{port,link,dev}_dbg
to standard pr_XXX() macros") and this is now causing compilation errors
for oxnas SATA driver due to usage of ata_link_printk().

Upstream has migrated to using the appropriate
ata_link_{err, warn, notice, info} calls a while ago so its not affected.

Lets do the same for oxnas SATA driver and use ata_link_err() instead of
ata_link_printk().
