[PATCH v3 4/4] logging: Change return type of virLogDaemonConfigFilePat to void

[Alexander Kuznetsov <kuznetsovam@xxxxxxxxxxxx>]

This function return value is invariant since 18f3771, so change
its type and remove all dependent checks.

Found by Linux Verification Center (linuxtesting.org) with Svace.
