e38f98f5 - [AMDGPU][Scheduler] Fix usage of `TII.reMaterialize` (NFC) (#150259)

[AMDGPU][Scheduler] Fix usage of `TII.reMaterialize` (NFC) (#150259) Any non-zero `SubIdx` passed to the method is composed with the rematerialized instruction's first operand's subregister to determine the new register's subregister. In our case we want the new register to have the same subregister as the old one, so we should pass 0.
