virtio/vsock: remove redundant 'skb_pull()' call

Browse Source 
commit 6825e6b4f8 upstream.

Since we now no longer use 'skb->len' to update credit, there is no sense
to update skbuff state, because it is used only once after dequeue to
copy data and then will be released.

Fixes: 71dc9ec9ac ("virtio/vsock: replace virtio_vsock_pkt with sk_buff")
