console: newport_con: fix an issue about leak related system resources
A call of the function do_take_over_console() can fail here.
The corresponding system resources were not released then.
Thus add a call of iounmap() and release_mem_region()
together with the check of a failure predicate. and also
add release_mem_region() on device removal.
Fixes: e86bb8acc0fdc ("[PATCH] VT binding: Make newport_con support binding")
