Subject: [PATCH 2/2] accel/ivpu: avoid duplciate assignment

From: Arnd Bergmann <arnd@...db.de>

With extra warnings enabled, gcc warns about two assignments
of the same .mmap callback:

In file included from drivers/accel/ivpu/ivpu_drv.c:10:
include/drm/drm_accel.h:31:27: error: initialized field overwritten [-Werror=override-init]
   31 |         .mmap           = drm_gem_mmap
      |                           ^~~~~~~~~~~~
drivers/accel/ivpu/ivpu_drv.c:360:9: note: in expansion of macro 'DRM_ACCEL_FOPS'
  360 |         DRM_ACCEL_FOPS,
      |         ^~~~~~~~~~~~~~

Remove the unused local assignment.

Fixes: 20709aa9435b ("accel: Add .mmap to DRM_ACCEL_FOPS")
