nir: mark *prev_block as MAYBE_UNUSED in opt_peel_loop_initial_if

Only used, when asserts are enabled.

Fixes an unused-variable warning with gcc-8:
 ../../../src/compiler/nir/nir_opt_if.c: In function 'opt_peel_loop_initial_if':
 ../../../src/compiler/nir/nir_opt_if.c:109:15: warning: unused variable 'prev_block' [-Wunused-variable]
     nir_block *prev_block =
                ^~~~~~~~~~
