pinctrl: sprd: free maps on DT map failure

Browse Source 
sprd_dt_node_to_map() reserves map storage before adding mux and
configuration entries.  If a later operation fails, the error path only
frees the temporary configurations and leaves the map allocation reachable
through the output pointer.

Free the partially built map on failure.  The caller ignores the output
parameters when the mapping callback returns an error, so they do not need
to be reset after freeing the map.
