Fix in regular expression matching OSD ID on non-contenerized

deployment.
restart_osd_daemon.sh is used to discover and restart all OSDs on a
host. To do it the scripts loops the list of ceph-osd@ services in the
system. This commit fixes bug in the regular expression responsile for
extraction of OSDs - prior version uses `[0-9]{1,2}` expression
which is ignoring all OSDS which numbers are greater than 99 (thus
longer than 2 digits). Fix removed upper limit of digits in the number.
This problem existed in two places in the script.

Closes: #2964
