[PATCH 2/2] drm/nouveau: remove set but not used variable 'mem'

[zhengbin <zhengbin13@huawei.com>]

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/gpu/drm/nouveau/nouveau_ttm.c: In function nouveau_vram_manager_new:
drivers/gpu/drm/nouveau/nouveau_ttm.c:66:22: warning: variable mem set but not used [-Wunused-but-set-variable]
drivers/gpu/drm/nouveau/nouveau_ttm.c: In function nouveau_gart_manager_new:
drivers/gpu/drm/nouveau/nouveau_ttm.c:106:22: warning: variable mem set but not used [-Wunused-but-set-variable]

The first 'mem' is introduced by commit 9ce523cc3bf2 ("drm/nouveau:
separate buffer object backing memory from nvkm structures"),
but never used, so remove it.

The second 'mem' is not used since commit d7722134b825 ("drm/nouveau:
switch over to new memory and vmm interfaces")
