Add resource failure when in error state

Previously, a filemapper provider could fail to parse a file and enter
an "error state", while in which the flush method would fail with an
error. However, individual resource-level logs would indicate success.
The following is an example log output.

  err: Could not prefetch mcollective_config provider 'filemapper':
    /etc/puppetlabs/mcollective/server.cfg is malformed; " = fabl" did not
    match "(?-mix:^\s*(\S+)\s*=\s*(\S+)\s*$)"
  notice: /Stage[main]//Mcollective_config[foo.value2]/ensure: created
  err: Puppet::Type::Mcollective_config::ProviderFilemapper: filemapper is
    in an error state, refusing to flush file
    /etc/puppetlabs/mcollective/server.cfg
  notice: /Stage[main]//Mcollective_config[foo.value1]/ensure: created
  err: Puppet::Type::Mcollective_config::ProviderFilemapper: filemapper is
    in an error state, refusing to flush file
    /etc/puppetlabs/mcollective/server.cfg
  notice: Finished catalog run in 0.11 seconds

Note the notice messages incorrectly indicating that the resources were
successfully created (inbetween error messages that are less closely
tied to individual resources).

This commit adds a check to the create method such that if the provider
enters an error state the failure will occur per-resource, and not only at
the end when trying to flush the resources to disk.
