net: wan: fsl_ucc_hdlc: free tx_skbuff in uhdlc_memclean
When the device is removed all allocated resources should be freed.
In uhdlc_memclean the netdev transmit queue was already stopped. But at
this point we may have pending skb in the transmit queue which must be
freed. Therefore iterate over the tx_skbuff pointers and free all
pending skb. The issue was discovered by sashiko.
Tested on a ls1043a board running HDLC in bus mode on kernel 6.12.
