qed (gcc13): use u16 for fid to be big enough

gcc 13 correctly reports overflow in qed_grc_dump_addr_range():
In file included from drivers/net/ethernet/qlogic/qed/qed.h:23,
                 from drivers/net/ethernet/qlogic/qed/qed_debug.c:10:
drivers/net/ethernet/qlogic/qed/qed_debug.c: In function 'qed_grc_dump_addr_range':
include/linux/qed/qed_if.h:1217:9: error: overflow in conversion from 'int' to 'u8' {aka 'unsigned char'} changes value from '(int)vf_id << 8 | 128' to '128' [-Werror=overflow]

We do:
  u8 fid;
  ...
  fid = vf_id << 8 | 128;

Since fid is 16bit (and the stored value above too), fid should be u16,
not u8. Fix that.
