what about just `rtirq restart` on the sleep.d script (on thaw|resume) ?

warning. there's no state salvage being done on bad old rtirq script. in
fact `rtirq stop` is a plain nop by default, unless RTIRQ_RESET_ALL=1 is
set (cf. /etc/rtirq.conf aka. /etc/sysconfig/rtirq) which makes all
target irq service threads to reset to rtprio=50 but also to "normal"
scheduling class(SCHED_OTHER). might not on par with the times :)

note that `rtirq restart` is actually the same function as `rtirq stop`
immediately followed by `rtirq start`. however, as s the very same irq
service threads are at stake, this whole remark might not be an issue
after all:)
