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
