[PATCH] soc: fsl: dpio: remove set but not used 'addr_cena'

From: Jason Yan <yanaijie@huawei.com>

This addresses the following gcc warning with "make W=1":

drivers/soc/fsl/dpio/qbman-portal.c: In function
‘qbman_swp_enqueue_multiple_direct’:
drivers/soc/fsl/dpio/qbman-portal.c:650:11: warning: variable
‘addr_cena’ set but not used [-Wunused-but-set-variable]
  650 |  uint64_t addr_cena;
      |           ^~~~~~~~~
