net: qrtr: Fix early exit in del client and bye cmds

When del client and bye command packets are sent out, if there
is an error in sending, continue with the loop to send to the
rest of the clients. The current implementation bails out when
the send fails. This is causing dropping of these packets to
the rest of the clients.
