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.

18 /* Calculate counter clock-divider and count values to attain the
19 desired frequency RATE from the base frequency BASE_FREQ. The
20 counter is expected to have a clock-divider, which can divide the
21 system cpu clock by a power of two value from MIN_DIVLOG2 to
22 MAX_DIV_LOG2, and a word-size of COUNTER_SIZE bits (the counter
23 counts up and resets whenever it's equal to the compare register,
24 generating an interrupt or whatever when it does so). The returned
25 values are: *DIVLOG2 -- log2 of the desired clock divider and *COUNT
26 -- the counter compare value to use. Returns true if it was possible
27 to find a reasonable value, otherwise false (and the other return
28 values will be set to be as good as possible). */
