[SRU OEM-B][PATCH] UBUNTU: SAUCE: Bluetooth: btrsi: fix l2test data transfer issue

[Siva Rebbagondla]

From: Siva Rebbagondla <siva.rebbagondla at redpinesignals.com>

BugLink: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1781895
 
Observed bluetooth l2test is getting failed as skb->data is having some
extra bytes rather than expected size, which is Incorrect. Hence, removed
redundant bytes from skb using skb_trim().
