drm/i915: Remove redundant check on execlists interrupt

Since commit 4a118ecbe99c ("drm/i915: Filter out spurious execlists
context-switch interrupts") we probe execlists->active, and no longer
have to peek at the execlist interrupt to determine if the tasklet still
needs to be run to drain the ELSP.
