hanzhijian fa1589a697 drivers/analog: fix dead free and memory leak in mcp48xx and mcp47x6. 
mcp48xx_initialize() and mcp47x6_initialize() share the same two bugs
in their allocation error paths:

1. Dead code: when the first kmm_malloc() fails and priv is NULL, the
   code calls free(priv) which is a no-op on NULL.  Remove it.

2. Memory leak: when the second kmm_malloc() fails (dacdev), the
   function returns NULL without freeing the already-allocated priv.
   Add kmm_free(priv) before the return.
