[PATCH] kexec-tools: print error if kexec_file_load fails

[Hari Bathini]

Commit 4f77da634035 ("kexec-tools: Fix kexec_file_load(2) error
handling") introduced EFALLBACK for scenarios where fallbacking back
to kexec_load syscall is likely to work and dropped printing error
message for these scenarios. But printing error message for other
failure scenarios was inadvertently dropped. Restore printing error
message for such cases.
