lavapipe: fp16 flrp must also be lowered

Browse source 
Prevents failures with fp16 in lavapipe and Zink on lavapipe when
"nir/lower_flrp: Check and set shader_info::flrp_lowered" is
applied. Lowering with an incomplete mask on the first call to
nir_lower_flrp will prevent later calls (with the complete mask) from
doing anything.
