Suren Baghdasaryan e61c236dcf sched/psi: Fix OOB write when writing 0 bytes to PSI files 
commit 6fcca0fa48 upstream.

Issuing write() with count parameter set to 0 on any file under
/proc/pressure/ will cause an OOB write because of the access to
buf[buf_size-1] when NUL-termination is performed. Fix this by checking
for buf_size to be non-zero.
