LU-18773 osc: initialize index_orig in osc_brw_prep_request

This patch initializes index_orig in osc_brw_prep_request() to
fix the following error:

  In function 'osc_brw_prep_request':
  error: 'index_orig' may be used uninitialized in this function
  [-Werror=maybe-uninitialized]
       brwpg->pg->index = index_orig;
       ~~~~~~~~~~~~~~~~~^~~~~~~~~~~~
