iommu/vt-d: Remove redundant assignment to variable err
Variable err is being assigned a value that is never read. It is
either being re-assigned later on error exit paths, or never referenced
on the non-error path.
Cleans up clang scan build warning:
drivers/iommu/intel/dmar.c:1070:2: warning: Value stored to 'err' is
never read [deadcode.DeadStores]`
