kexec-uImage-arm64.c: Fix return value of uImage_arm64_probe()

Commit bf06cf2095e1 ("kexec/uImage: probe to identify a corrupted image"),
defined the 'uImage_probe_kernel()' function return values and
correspondingly ;uImage_arm64_probe()' returns the same (0 -> If the
image is valid 'type' image, -1 -> If the image is corrupted and
1 -> If the image is not a uImage).

This causes issues because, in later patches we introduce zImage
support for arm64, and since it is probed after uImage, the return
values from 'uImage_arm64_probe()' needs to be fixed to make sure
that kexec will not return with an invalid error code.

Now, 'uImage_arm64_probe()' returns the following values instead:
  0 - valid uImage.
 -1 - uImage is corrupted.
  1 - image is not a uImage.
