wifi: mt76: mt7996: fix uninitialized variable in mt7996_irq_tasklet()
[ Upstream commit 1ac710a6e8545c6df7a292f167dd088880a74c05 ]
Set intr1 to 0 in mt7996_irq_tasklet() in order to avoid possible
uninitialized variable usage if wed is not active for hif2.
Fixes: 83eafc9251d6 ("wifi: mt76: mt7996: add wed tx support")
