KEXEC: Call ima_kexec_cmdline to measure the boot command line args
During soft reboot(kexec_file_load) boot command line
arguments are not measured.
Call ima hook ima_kexec_cmdline to measure the boot command line
arguments into IMA measurement list.
- call ima_kexec_cmdline from kexec_file_load.
- move the call ima_add_kexec_buffer after the cmdline
args have been measured.
