kexec: fix probe error codes and error propagation

While debugging a misleading error on s390x where kexec -s reported
"syscall kexec_file_load not available" instead of the actual EINVAL
from a kernel command line that exceeded the architecture limit, we
found that some kexec image probe functions return -EINVAL instead of
-ENOEXEC for format mismatches, and kexec_image_probe_default() has a
bug where it returns whatever the last loader returned rather than
always returning -ENOEXEC when no loader matches.

[...]

Applied to kexec-fixes branch of liveupdate/linux.git tree, thanks!
