The commit a85ee18c7900 ("kexec_file: print out debugging message
if required") has added general code printing in kexec_file_load(),
but not in kexec_load().
As a result, when using '-d' for the kexec_load interface,
print nothing in the kernel space.
And print out type/start/head of kimage and flags to help debug.
