Horia Geantă bbf2234494 crypto: caam - fix DMA API leaks for multiple setkey() calls 
setkey() callback may be invoked multiple times for the same tfm.
In this case, DMA API leaks are caused by shared descriptors
(and key for caamalg) being mapped several times and unmapped only once.
Fix this by performing mapping / unmapping only in crypto algorithm's
cra_init() / cra_exit() callbacks and sync_for_device in the setkey()
tfm callback.
