mwifiex: Avoid memset() over-write of WEP key_material
In preparation for FORTIFY_SOURCE performing compile-time and run-time
field bounds checking for memset(), avoid intentionally writing across
neighboring array fields.
When preparing to call mwifiex_set_keyparamset_wep(), key_material is
treated very differently from its structure layout (which has only a
single struct mwifiex_ie_type_key_param_set). Instead, add a new type to
the union so memset() can correctly reason about the size of the
structure.
Note that the union ("params", 196 bytes) containing key_material was
not large enough to hold the target of this memset(): sizeof(struct
mwifiex_ie_type_key_param_set) == 60, NUM_WEP_KEYS = 4, so 240
bytes, or 44 bytes past the end of "params". The good news is that
it appears that the command buffer, as allocated, is 2048 bytes

getting clobbered.

rtl8xxxu: avoid parsing short RX packet
One USB data buffer can contain multiple received network
packets. If that's the case, they're processed this way:
1. Original buffer is cloned
2. Original buffer is trimmed to contain only the first
network packet
3. This first network packet is passed to network stack
4. Cloned buffer is trimmed to eliminate the first network
packet
5. Repeat with the cloned buffer until there are no more
network packets inside
However, if the space remaining in original buffer after
the first network packet is not enough to contain at least
another network packet descriptor, it is not cloned.
The loop parsing this packets ended if remaining space == 0.
But if the remaining space was > 0 but < packet descriptor
size, another iteration of the loop was done, processing again
the previous packet because cloning didn't happen. Moreover,
the ownership of this packet had been passed to network
stack in the previous iteration.
This patch ensures that no extra iteration is done if the
remaining size is not enough for one packet, and also avoid
the first iteration for the same reason.
Probably this doesn't happen in practice, but can happen
theoretically.

mt76: mt7921: fix reset under the deep sleep is enabled
To fix possibly the race to access register between the WiFi reset
and the other context that is caused by explicitly cancelling ps_work
and wake_work to break PM_STATE consistency.
Deep sleep would cause the hardware into the inactive state,
so we forcely put device drv_own state before we start to reset.
The patch also ignore the reset request when the procedure is in
progress to avoid the consecutive WiFi resets.
