Subject: [PATCH] journal: fail silently in sd_j_sendv() if journal is

 unavailable

"syslog(3) and sd_journal_print() may largely be used interchangeably

functionality-wise" according to sd_journal_print(3). This socket

should be always available except in rare circumstatances, and we

don't random applications to fail on logging, so let's do what syslog

did. The alternative of forcing all callers to do error handling for

this rare case doesn't really have any benefits, since if they can't

log there isn't much they can do anyway.
