Subject: [PATCH] Fix domain decomposition overwriting muscl_order

The IGR conditional block unconditionally reset recon_order to
weno_order in its else branch, overwriting the muscl_order that
was correctly set by the recon_type check above. Remove the else
branch so the original recon_order is preserved when IGR is inactive.
