kernel/kexec: change the prototype of kimage_map_segment()
commit fe55ea85939efcbf0e6baa234f0d70acb79e7b58 upstream.
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.

Fixes: 07d24902977e ("kexec: enable CMA based contiguous allocation")
