[PATCH 1/1] Monitor: Allow no PID in check_one_sharer()

[Mateusz Kusiak <mateusz.kusiak@intel.com>]

Commit 5fb5479ad100 ("Monitor: open file before check in
check_one_sharer()") introduced a regression that prohibits monitor
from starting if PID file does not exist.

Add check for no PID file.
Add missing fclose().
