intel/compiler: Silence warning about value that may be used uninitialized

Browse source 
For some reason, this warning only occurs for me in release builds.

In file included from src/intel/compiler/brw_nir_lower_mem_access_bit_sizes.c:25:0:
src/intel/compiler/brw_nir_lower_mem_access_bit_sizes.c: In function ‘brw_nir_lower_mem_access_bit_sizes’:
src/compiler/nir/nir_builder.h:501:26: warning: ‘src_swiz[2]’ may be used uninitialized in this function [-Wmaybe-uninitialized]
       alu_src.swizzle[i] = swiz[i];
       ~~~~~~~~~~~~~~~~~~~^~~~~~~~~
src/intel/compiler/brw_nir_lower_mem_access_bit_sizes.c:225:16: note: ‘src_swiz[2]’ was declared here
       unsigned src_swiz[4];
                ^~~~~~~~
