[PATCH] [i915] Fix another use of the wrong interlace mask to return to progressive mode

[Christian Schmidt]

intel_display.c:            pipeconf |= PIPECONF_INTERLACE_W_FIELD_INDICATION;
intel_display.c:            pipeconf &= ~PIPECONF_INTERLACE_MASK; /* progressive */
intel_display.c:            pipeconf |= PIPECONF_INTERLACE_W_FIELD_INDICATION;
intel_display.c:            pipeconf &= ~PIPECONF_INTERLACE_W_FIELD_INDICATION; /* progressive */

The second setting of progressive mode should use PIPECONF_INTERLACE_MASK, too.
