Stephane Grosjean 1f5d203906 can: peak/pcie_fd: fix potential bug in restarting tx queue
commit 91785de6f9 upstream.

Don't rely on can_get_echo_skb() return value to wake the network tx
queue up: can_get_echo_skb() returns 0 if the echo array slot was not
occupied, but also when the DLC of the released echo frame was 0.
