Some generators would ignore the value and warn, possibly logging twice. Other
generators would treat the failure as fatal, even though it probably doesn't
matter too much if drop-in with the timeout is not written.

fstab_filter_options() can only fail with -ENOMEM, which we want to treat as
a fatal error, so use log_error and drop ", ignoring".

Simplify the function to always log uniformly and simplify the callers.
