[Smartswitch] Fix the values being set for reboot_status call during smartswitch DPU reboot

[gpunathilell]

During smartswitch DPU reboot we query the rebootstatus call to check the current status. This is currently failing on DPU because the RebootStatus enum is not serializable:

root@sonic:/home/admin# dbus-send --system --print-reply --dest=org.SONiC.HostService.reboot /org/SONiC/HostService/reboot org.SONiC.HostService.reboot.get_reboot_status
Error org.freedesktop.DBus.Python.TypeError: Traceback (most recent call last):

TypeError: Object of type RebootStatus is not JSON serializable

So setting it to value everywhere to fix the issue

Should we also change the test case
test_get_reboot_status_active
and
test_get_reboot_status_inactive

[gpunathilell]

Updated test

[rameshraghupathy]

@gpunathilell self.reboot_status_flag can sometimes be None, Can you please handle that case also? Do the same everywhere.

[gpunathilell]

@rameshraghupathy self.reboot_status_flag should ideally never be empty. since we are populating it with default values on initialization of reboot class

@vvolam I have changed the output of the status to display the name of the status instead of the value because it is more readable, let me know if it affects anything else and I can revert it
