Lucas Stach 58f804da14 drm/etnaviv: check for reaped mapping in etnaviv_iommu_unmap_gem ...

commit e168c25526cd0368af098095c2ded4a008007e1b upstream.

When the mapping is already reaped the unmap must be a no-op, as we
would otherwise try to remove the mapping twice, corrupting the involved
data structures.
