nuttx: use lib_free for memory de-allocation after strdup or asprintf

Browse Source 
The memory allocated with strdup and asprintf is done via lib_malloc
so we need to use lib_free to deallocate memory otherwise the assertion
"Free memory from the wrong heap" is hit with flat mode and user separated
heap enabled mode.
