NOMMU: Fix cleanup handling in ramfs_nommu_get_umapped_area()
Fix cleanup handling in ramfs_nommu_get_umapped_area() by only freeing the
number of pages that find_get_pages() said it had returned (nr) rather than
attempting to free the number of pages we asked for (lpages) - thus avoiding
the situation whereby put_page() may be handed NULL pointers if
find_get_pages() returned fewer pages that were requested.
Also avoid a warning about nr being uninitialised and the need for an
if-statement in the cleanup path by using appropriate gotos.
