i965/fs: Use the correct base_mrf for spilling pairs in SIMD8
Before, we were hard-coding the base_mrf based on dispatch width not number
of registers spilled at a time. This caused us to emit instructions with a
base_mrf or 14 and a mlen of 3 so we used the magical non-existant m16
register. This fixes the problem.
