mm/shmem: remove unneeded assignments in shmem_get_folio_gfp()

After the rework of shmem_get_folio_gfp() to use a folio, the local variable hindex is only needed to be set once before passing it to shmem_add_to_page_cache(). Remove the unneeded initialization and assignments of the variable hindex before the actual effective assignment and first use. No functional change. No change in object code.
