[Intel-gfx] [PATCH] drm/i915/guc: Don't use pr_err when not necessary

[John.C.Harrison@Intel.com]

From: John Harrison <John.C.Harrison@Intel.com>

A bunch of code was copy/pasted using pr_err as the default way to
report errors. However, drm_err is significantly more useful in
identifying where the error came from. So update the code to use that
instead.
