mesa/st: don't set lower_fdot in draw_nir_options

Browse source 
lower_fdot outputs fsum ops like fsum3, which in this stage may
go through nir_to_tgsi paths and tgsi doesn't implement them.
This hits an assert in ntt_emit_alu:

feedback: ../src/gallium/auxiliary/nir/nir_to_tgsi.c:1804:
ntt_emit_alu: Assertion `!"" "Unknown NIR opcode"' failed.
