pb-4969: Fixed issue with backuplocation CR variable, which was causing

the nfs backup issue.

	- backuplocation CR variable scope was lost inside the if
	  condtion. Because of this the nfs parameters are not passed to kopia job.
	- The kopia writes the snapshot file directly  inside the job
	  pod file system and files are lost once the pod is completed.
	- Since the nfs parameters are not passed, the nfs pvc was not
	  getting mounted inside the nfs job pod.
