drm_dp_dpcd_read/write already has debug error message.
Drop redundant error messages which gives false
status even if correct value is read in drm_dp_dpcd_read().
Fixes: 9488a030ac91 ("drm/i915: Add support for enabling link status and recovery")

I guess the only problem is it gets harder to associate the preceding
low level error messages with intel_dp_check_link_service_irq(). *shrug*

Yes. https://patchwork.freedesktop.org/series/93025/#rev3
Should I add debug prints how Imre suggested in other IRQ func
to make it generic or should it be dropped from here too?
Quoting imre
"Yes, that's why I suggested to return for the '0 value read' case
without any message printed, but still keep the message for the case
when the drm_dp_dpcd_readb() fails."
"Ok, it's good to keep them in sync at least, so I'm ok with removing
the debug messages from here too."
Please let me know what is the better approach.
