Resolve an inconsistency between libX11 and Xserver over GetModifierMapping

Browse source 
libX11 ModMap.c believes that GetModifierMapping can never return an error

Xserver devices.c believes that GetModifierMapping can return an error if
the ModMap couldn't be generated

According to the protocol document I have, libX11 is right, so adjust the
server to send back an empty modmap if one couldn't be made...
