The pointer map is being initialized with a value that is never
read, it is being re-assigned later on in a for-loop. The
initialization is redundant and can be removed.

Cleans up clang scan build warning:
drivers/gpu/drm/i915/gvt/interrupt.c:346:28: warning: Value stored to
'map' during its initialization is never read [deadcode.DeadStores]
