lima/ppir: fix lod bias src

ppir has some code that operates on all ppir_src variables, and for that
uses ppir_node_get_src.
lod bias support introduced a separate ppir_src that is inaccessible by
that function, causing it to be missed by the compiler in some routines.
Ultimately this caused, in some cases, a bug in const lowering:

  .../pp/lower.c:42: ppir_lower_const: Assertion `src != NULL' failed.

This fix moves the ppir_srcs in ppir_load_texture_node together so they
don't get missed.
