2023-01-16wifi: mt7601u: fix an integer underflowJisoo Jang
Fix an integer underflow that leads to a null pointer dereference in 'mt7601u_rx_skb_from_seg()'. The variable 'dma_len' in the URB packet could be manipulated, which could trigger an integer underflow of 'seg_len' in 'mt7601u_rx_process_seg()'. This underflow subsequently causes the 'bad_frame' checks in 'mt7601u_rx_skb_from_seg()' to be bypassed, eventually leading to a dereference of the pointer 'p', which is a null pointer. Ensure that 'dma_len' is greater than 'min_seg_len'. Found by a modified version of syzkaller.

When adding WED support, mt76_dma_add_buf was accidentally changed to set the skip_buf0 flag for tx buffers on the wrong queue descriptor entry. Additionally, there is a rxwi leak when rx buffer allocation fails. Fix this and make the code more readable by adding a separate function for adding rx buffers.
