oem: Fix to remove extra system dump

An unwanted system dump is being generated if the resource dump is
initiated from hypervisor with an empty vsp string. So the fix here
is to additionally check the resource dump progress status and block
sending the command to hypervisor if the status is not in progress.

Tested by initiating a resource dump from hypervisor with an empty
string and observed that extra system dump was not getting generated
after the fix.
