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 * Core file format: The core file is written in such a way that gdb
16 * can understand it and provide useful information to the user (under
17 * linux we use the `trad-core' bfd).
18 *
19 * The actual file contents are as follows:
20 * UPAGE: 1 page consisting of a user struct that tells gdb
21 * what is present in the file. Directly after this is a
22 * copy of the task_struct, which is currently not used by gdb,
23 * but it may come in handy at some point. All of the registers
24 * are stored as part of the upage. The upage should always be
25 * only one page.
26 * DATA: The data area is stored. We use current->end_text to
27 * current->brk to pick up all of the user variables, plus any memory
28 * that may have been sbrk'ed. No attempt is made to determine if a
29 * page is demand-zero or if a page is totally unused, we just cover
30 * the entire range. All of the addresses are rounded in such a way
31 * that an integral number of pages is written.
32 * STACK: We need the stack information in order to get a meaningful
33 * backtrace. We need to write the data from usp to
34 * current->start_stack, so we round each of these off in order to be
35 * able to write an integer number of pages.
