Lakshmi Ramasubramanian 9c5d89bc10 arm64: kexec: Fix missing error code 'ret' warning in load_other_segments() 
Since commit ac10be5cdb ("arm64: Use common
of_kexec_alloc_and_setup_fdt()"), smatch reports the following warning:

  arch/arm64/kernel/machine_kexec_file.c:152 load_other_segments()
  warn: missing error code 'ret'

Return code is not set to an error code in load_other_segments() when
of_kexec_alloc_and_setup_fdt() call returns a NULL dtb. This results
in status success (return code set to 0) being returned from
load_other_segments().

Set return code to -EINVAL if of_kexec_alloc_and_setup_fdt() returns
NULL dtb.
