xilinx: common: fix board_late_init_xilinx()

Compiling with GCC-12 leads to an error:

    +board/xilinx/common/board.c:479:37: error: the comparison will always
     evaluate as 'true' for the address of 'mac_addr' will never be NULL
     [-Werror=address]
    +  479 |                                 if (!desc->mac_addr[i])
    +      |                                     ^

Remove the redundant check.
