[lttng-dev] [PATCH lttng-tools] Fix: unchecked return value in low throughput test

[Mathieu Desnoyers]

Found by Coverity:

CID 1019967 (#1 of 1): Unchecked return value from library
(CHECKED_RETURN)2. check_return: Calling poll(NULL, 0UL, 60000) without
checking return value. This library function may fail and return an
error code.

We really don't care whether this poll succeeds or not.
