kernel/kexec: change the prototype of kimage_map_segment()

The kexec segment index will be required to extract the corresponding
information for that segment in kimage_map_segment().  Additionally,
kexec_segment already holds the kexec relocation destination address and
size.  Therefore, the prototype of kimage_map_segment() can be changed.
