Subject: [PATCH 06/15] wifi: iwlwifi: mvm: initialize seq variable

From: Tom Rix <[email protected]>

Clang static analysis reports this issue
d3.c:567:22: warning: The left operand of '>' is
a garbage value
if (seq.tkip.iv32 > cur_rx_iv32)
~~~~~~~~~~~~~ ^

seq is never initialized. Call ieee80211_get_key_rx_seq() to
initialize seq.

Fixes: 0419e5e672d6 ("iwlwifi: mvm: d3: separate TKIP data from key iteration")
