[PATCH v2] drm/gpusvm: set has_dma_mapping inside mapping loop

[Matthew Brost]

From: Dafna Hirschfeld <dafna.hirschfeld at intel.com>

The 'has_dma_mapping' flag should be set once there is a
mapping so it could be unmapped in case of error.

v2:
- Resend for CI

Fixes: 99624bdff867 ("drm/gpusvm: Add support for GPU Shared Virtual Memory")
