[PATCH] rasdaemon: don't emit error syslog when exiting normally

[Ivan Delalande <colona@arista.com>]

Tidy up read_ras_event_all_cpus exit path so that it returns 0 when
exiting normally after receiving a signal. It would return -1 and make
the caller emit "Huh! something got wrong. Aborting." in this case.

Also add missing error message for ras_mc_event_opendb and fix the
grammar a bit in the message above.

Fixes: a7b6a0464fba ("rasdaemon: add signal handling for the cleanup")
