drm/msm: use strscpy instead of strncpy

Browse source 
Using strncpy can result in non-NULL-terminated destination string. Use
strscpy instead. This fixes following warning:

drivers/gpu/drm/msm/msm_fence.c: In function ‘msm_fence_context_alloc’:
drivers/gpu/drm/msm/msm_fence.c:25:9: warning: ‘strncpy’ specified bound 32 equals destination size [-Wstringop-truncation]
   25 |         strncpy(fctx->name, name, sizeof(fctx->name));
      |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
