Alan Coopersmith f089b652cd os: handle memory allocation failure in get_mcast_options() ...

Since this is in initial startup, and other errors in this function are
already fatal, just make allocation failure of this small structure be
fatal as well, since if the X server is already out of memory it will
be dying soon anyway.

Reported in #1817:
xwayland-24.1.6/redhat-linux-build/../os/xdmcp.c:1514:13:
 warning[-Wanalyzer-possible-null-dereference]:
  dereference of possibly-NULL ‘mcastinfo’
xwayland-24.1.6/redhat-linux-build/../os/xdmcp.c:1513:25:
 acquire_memory: this call could return NULL
xwayland-24.1.6/redhat-linux-build/../os/xdmcp.c:1514:13:
 danger: ‘mcastinfo’ could be NULL: unchecked value from (9)
