[PATCH v2] thermal/core: avoid memory leak

[Muhammad Usama Anjum <musamaanjum@gmail.com>]

When memory allocation for cdev is successful but ida_simple_get fails,
branch to out_kfree_cdev label happens and cdev isn't freed. There are
also some other cases in which the memory can leak. Fix it by freeing cdev.
