Fix a memory leak that occurs when reading the fw_info
file all the way, since we return NULL indicating no
more data, but don't free the status tracking object.

kernel: wifi: iwlwifi: fw: fix memory leak in debugfs
In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: fw: fix memory leak in debugfs
Fix a memory leak that occurs when reading the fw_info
file all the way, since we return NULL indicating no
more data, but don't free the status tracking object.
Statement: A memory leak in iwlwifi’s debugfs fw_info reader caused the per-read iterator state to never be freed at end-of-file. The fix frees the state object when the iterator returns NULL. Impact is limited to privileged local users reading debugfs.
