[ Upstream commita1c95dd5bc] 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.
