Subject: [PATCH] crypto/scheduler: fix strncpy

[ upstream commit 6af3b03547d7499e8875f7e32effba172140bbfe ]

The coverity issue was not completely fixed, since strncpy
should not be called with max length.
Instead, snprintf is used as a safer option.

Coverity issue: 143431
Fixes: d040aca67170 ("crypto/scheduler: fix strings not null terminated")
