Documentation: livepatch: module-elf-format: Remove local klp_modinfo definition

Since apply_relocate_add() requires access to a module's section headers,

symbol table, and relocation section indices, Elf information is preserved for

livepatch modules and is made accessible by the module loader through

module->klp_info, which is a klp_modinfo struct. When a livepatch module loads,

this struct is filled in by the module loader. Its fields are documented below::

	struct klp_modinfo {

		Elf_Ehdr hdr; /* Elf header */

		Elf_Shdr *sechdrs; /* Section header table */

		char *secstrings; /* String table for the section headers */

		unsigned int symndx; /* The symbol table section index */

	};

module->klp_info, which is a :c:type:`klp_modinfo` struct. When a livepatch module

loads, this struct is filled in by the module loader.
