Subject: nv50/ir: OP_JOIN is a flow instruction

nv50/ir: OP_JOIN is a flow instruction

OP_JOIN instructions are assumed to be flow instructions and mercilessly
casted to FlowInstruction.

This patch fixes an instance where an OP_JOIN is created as a plain
instruction. This can cause crashes in the ir printer.
