Olaf Hering d172da1bb4 stubdom: another for fix for lwip compile 
stubdom/lwip-x86_64/src/core/dhcp.c: In function 'dhcp_create_request':
stubdom/lwip-x86_64/src/core/dhcp.c:1361:64: error: array subscript is above array bounds

The previous attempt to fix the failure above worked fine in SLE11,
openSUSE 13.1 and newer. But gcc-4.5 as included in openSUSE 11.4 still
failed to compile. To fix compilation also with this version of gcc move
the range check right into the code instead of assigning it to a
temporary variable.

stubdom/lwip-x86_64/src/core/dhcp.c:1359:71: error: array subscript is above array bounds [-Werror=array-bounds]
     dhcp->msg_out->chaddr[i] = (i < netif->hwaddr_len) ? netif->hwaddr[i] : 0/* pad byte*/;

gcc can not know if hwaddr_len exceeds the hwaddr array size,
so force an upper limit to assist gcc.
