nv50,nvc0: fix clear buffer acceleration

Two things were off:
 - valid range was not updated, which could affect waiting for future
   maps
 - fencing was done manually instead of using the *_resource_validate
   helper, which resulted in a missed dirty buffer flag being set

Fixes: KHR-GL45.direct_state_access.buffers_clear
