i965/vs: Fix invalid array access in copy propagation.

Accessing virtual_grf_reg_map[inst->dst.reg] is invalid if
inst->dst.file != GRF.  Since is_direct_copy already implies a GRF
destination, we can just move the check earlier.

Fixes a regression in commit 07ee9f374f2946f852896e9264c7fa83eafc3f16.
