Subject: [PATCH net v2 15/21] wil6210: set .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: 2be7d22f0625 ("wireless: add new wil6210 802.11ad 60GHz driver")
Fixes: 0b39aaf2f203 ("wil6210: Tx mgmt frame from debugfs")
Fixes: c5b3a6582b1e ("wil6210: Add support for setting RBUFCAP configuration")
Fixes: 3277213feb1b ("wil6210: ADDBA/DELBA flows")
