i965/fs: initialize src as reg_undef for texture opcodes on Gen5/6.
Commit 07af0ab changed fs_inst to have 0 sources for texture opcodes
in emit_texture_gen5 (Ironlake, Sandybrige) while fs_generator still
uses a single source from brw_reg struct. Patch sets src as reg_undef
which matches the behavior before the constructor got changed.
