[PATCH v2] xkb: Fix NULL pointer dereference in XkbAllocSrvLedInfo

[Dirk Wallenstein]

The second branch is an extension of the first, where the only
assignment of an XkbSLI_IsDefault flag takes place. That flag says that
the maps and names fields are pointers into xkbInfo->desc and not to
memory allocated with the XkbSrvLedInfoRec.
There is no allocation necessary in the second branch, and the only task
is to update the relation to xkbInfo->desc.
To accomplish that, the XkbSrvLedInfoPtr from the keyboard feedback has
to be used.
