ath10k: fix memory overwrite of the WoWLAN wakeup packet pattern
In function ath10k_wow_convert_8023_to_80211(), it will do memcpy for
the new->pattern, and currently the new->pattern and new->mask is same
with the old, then the memcpy of new->pattern will also overwrite the
old->pattern, because the header format of new->pattern is 802.11,
its length is larger than the old->pattern which is 802.3. Then the
operation of "Copy frame body" will copy a mistake value because the
body memory has been overwrite when memcpy the new->pattern.
Assign another empty value to new_pattern to avoid the overwrite issue.
Tested-on: QCA6174 hw3.2 SDIO WLAN.RMH.4.4.1-00049
Fixes: fa3440fa2fa1 ("ath10k: convert wow pattern from 802.3 to 802.11")
