Ilia Gavrilov 7ff230d853 llc: fix data loss when reading from a socket in llc_ui_recvmsg() 
commit 239af1970bcb039a1551d2c438d113df0010c149 upstream.

For SOCK_STREAM sockets, if user buffer size (len) is less
than skb size (skb->len), the remaining data from skb
will be lost after calling kfree_skb().

To fix this, move the statement for partial reading
above skb deletion.

Found by InfoTeCS on behalf of Linux Verification Center (linuxtesting.org)
