dmaengine: ste_dma40: Fix probe LCLA free
When LCLA is placed in ESRAM, d40_probe() stores a devm_ioremap()
address in lcla_pool.base and leaves base_unaligned unset. The
destroy_cache error path can then pass the ioremap address to
free_pages().
Only free lcla_pool.base with free_pages() when the driver allocated the
LCLA pool from normal memory. The ESRAM mapping is devm-managed.
