NULL Pointer Dereference

Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
wifi: iwlwifi: mld: avoid panic on init failure<br />
<br />
In case of an error during init, in_hw_restart will be set, but it will<br />
never get cleared.<br />
Instead, we will retry to init again, and then we will act like we are in a<br />
restart when we are actually not.<br />
<br />
This causes (among others) to a NULL pointer dereference when canceling<br />
rx_omi::finished_work, that was not even initialized, because we thought<br />
that we are in hw_restart.<br />
<br />
Set in_hw_restart to true only if the fw is running, then we know that<br />
FW was loaded successfully and we are not going to the retry loop.
