soc: qcom: bam_dmux: Use skb tail helper functions 



Accessing or modifying the tail member of a skb should be done through the
helper functions as the tail member can be represented as one of multiple
forms internally in the skb.

Use the skb tail helper functions where appropiate to access or modify the
tail member.
