kexec: dont initialise regions in reserve_memory()

There is no need to initialise efi_memmap_res and boot_param_res in
reserve_memory() for the initial xen domain as it is done in
machine_kexec_setup_resources() using values from the kexec hypercall.

15 If you say Y here, it will be possible to remotely debug the kernel
16 using gdb. This enlarges your kernel ELF image disk size by several
17 megabytes and requires a machine with more than 16 MB, better 32 MB
18 RAM to avoid excessive linking time. This is only useful for kernel
19 hackers. If unsure, say N.

48 If you are using GDB for remote debugging over a serial port and
49 would like kernel messages to be formatted into GDB $O packets so
50 that GDB prints them as program output, say 'Y'.
