[PATCH 2/2] powerpc: If kexec_build_elf_info() fails return immediately from elf64_load()

[Lakshmi Ramasubramanian]

Uninitialized local variable "elf_info" would be passed to
kexec_free_elf_info() if kexec_build_elf_info() returns an error
in elf64_load().

If kexec_build_elf_info() returns an error, return the error
immediately.
