00e8046b39 wifi: iwlwifi: mvm: Fix response handling in iwl_mvm_send_recovery_cmd()
[ Upstream commit 07a6e3b78a65f4b2796a8d0d4adb1a15a81edead ]

1. The size of the response packet is not validated.
2. The response buffer is not freed.

Resolve these issues by switching to iwl_mvm_send_cmd_status(),
which handles both size validation and frees the buffer.

[ Upstream commit e50a88e5cb8792cc416866496288c5f4d1eb4b1f ]

This will allow to reconnect immediately instead of leaving the
connection in a limbo state.

bda6f9fe3e wifi: iwlwifi: mvm: don't read past the mfuart notifcation
[ Upstream commit 4bb95f4535489ed830cf9b34b0a891e384d1aee4 ]

In case the firmware sends a notification that claims it has more data
than it has, we will read past that was allocated for the notification.
Remove the print of the buffer, we won't see it by default. If needed,
we can see the content with tracing.

This was reported by KFENCE.
