BUG/MINOR: quic: break for error on sendto

Browse Source 
If sendto returns an error, we should not retry the call and break from
the sending loop. An exception is made for EINTR which allows to retry
immediately the syscall.

This bug caused an infinite loop reproduced when the process is in the
closing state by SIGUSR1 but there is still QUIC data emission left.
