[Intel-gfx] [PATCH 4/4] i915/gvt: remove spaces in pr_debug "gvt: core:" etc prefixes

Taking embedded spaces out of existing prefixes makes them better
class-prefixes; simplifying the extra quoting needed otherwise:

  $> echo format "^gvt: core:" +p >control
vs
  $> echo format ^gvt:core: +p >control

Dropping the internal spaces means that quotes are only needed when
the trailing space is required; they more distinctively signal that
requirement.

Consider a generic drm-debug example:

  # turn off ATOMIC reports
  echo format "^drm:atomic: " -p > control

  # turn off all ATOMIC:* reports, including any sub-categories
  echo format "^drm:atomic:" -p > control

  # turn on ATOMIC:FAIL: reports
  echo format "^drm:atomic:fail: " +p > control

Removing embedded spaces in the class-prefixes simplifies the
corresponding match-prefix.  This means that "quoted" match-prefixes
are only needed when the trailing space is desired, in order to
exclude explicitly sub-categorized pr-debugs; in this example,
"drm:atomic:fail:".
