[PATCH] wifi: mt76: mt7921: clear WM2 from MT7902 RX all_complete_mask

[Mahesh Saran]

MT7902 does not have an MCU_WA ring and sets wm2_complete_mask to 0.
However, commit 83c65e82e5b2 ("wifi: mt76: connac2: apply new rx
all_complete_mask") populated all_complete_mask in the shared irq_map
template with MT_INT_RX_DONE_ALL, which includes MT_INT_RX_DONE_WM2.

Because MT7902 duplicates irq_map but only clears wm2_complete_mask,
its all_complete_mask still contains MT_INT_RX_DONE_WM2. This leaves
the MT7902 RX interrupt configuration inconsistent: the aggregate RX
completion mask includes WM2 even though the corresponding RX queue is
not present on MT7902.

Clear MT_INT_RX_DONE_WM2 from all_complete_mask for MT7902 as well.
