Dinghao Liu 1e9d707233 crypto: ccp - fix memleak in ccp_init_dm_workarea 
[ Upstream commit a1c95dd5bc ]

When dma_map_single() fails, wa->address is supposed to be freed
by the callers of ccp_init_dm_workarea() through ccp_dm_free().
However, many of the call spots don't expect to have to call
ccp_dm_free() on failure of ccp_init_dm_workarea(), which may
lead to a memleak. Let's free wa->address in ccp_init_dm_workarea()
when dma_map_single() fails.

Fixes: 63b945091a ("crypto: ccp - CCP device driver and interface support")
