Vakul Garg 3862de1f6c crypto: caam - fix job ring cleanup code 
The job ring init function creates a platform device for each job ring.
While the job ring is shutdown, e.g. while caam module removal, its
platform device was not being removed. This leads to failure while
reinsertion and then removal of caam module second time.

The following kernel crash dump appears when caam module is reinserted
and then removed again. This patch fixes it.
