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.
