Oliver Hartkopp e382fea8ae can: isotp: restore accidentally removed MSG_PEEK feature
In commit 42bf50a179 ("can: isotp: support MSG_TRUNC flag when
reading from socket") a new check for recvmsg flags has been
introduced that only checked for the flags that are handled in
isotp_recvmsg() itself.

This accidentally removed the MSG_PEEK feature flag which is processed
later in the call chain in __skb_try_recv_from_queue().

Add MSG_PEEK to the set of valid flags to restore the feature.

Fixes: 42bf50a179 ("can: isotp: support MSG_TRUNC flag when reading from socket")
