rtla: Fix __set_sched_attr error message
[ Upstream commit 941a53c39a151e9aceef153cdfaed0f166ba01b7 ]
rtla's function __set_sched_attr() was borrowed from stalld, but I
forgot to update the error message to something meaningful for rtla.
Update the error message from:
boost_with_deadline failed to boost pid PID: STRERROR
to a proper one:
Failed to set sched attributes to the pid PID: STRERROR
