qed: Fix uninitialized data in aRFS infrastructure

Current memset is using incorrect type of variable, causing the
upper-half of the strucutre to be left uninitialized and causing:

  ethernet/qlogic/qed/qed_init_fw_funcs.c: In function 'qed_set_rfs_mode_disable':
  ethernet/qlogic/qed/qed_init_fw_funcs.c:993:3: error: '*((void *)&ramline+4)' is used uninitialized in this function [-Werror=uninitialized]
