Apparently sec_base doesn't mean relocated symbol value, which seems a
copy-pasting error in the comment. Assigned with the address of section
indexed by sym->st_shndx, it should represent base address of the
relevant section. Let's fix the comment to avoid possible confusion.

Fixes: 838b3e28488f ("RISC-V: Load purgatory in kexec_file")
