Subject: [PATCH net 050/117] iwlwifi: runtime: set _FWRT_DEBUGFS_READ_WRITE_FILE_OPS.owner to THIS_MODULE

If THIS_MODULE is not set, the module would be removed while debugfs is
being used.
It eventually makes kernel panic.

Fixes: 93b167c13a3a ("iwlwifi: runtime: sync FW and host clocks for logs")
