i915/i915_gem_context: Remove debug message in i915_gem_context_create_ioctl

We know that as long as GEM context create ioctl succeeds, a context was
created. There is no need to write about it, especially when such a message
heavily pollutes dmesg and makes debugging actual errors harder.

Since commit baa89ba3f1 ("drm/i915/gem: initial conversion to new
logging macros using coccinelle"), the logging for creating a new user
context was moved under the driver debug output (for lack of a means for
per-user logs, and a lack of user-focused drm.debug parameter). This
only reveals how obnoxious having that spam be part of the driver debug
logs, so remove it. [ from Chris Wilson ]
