Fix a problem with parallel workers being unable to restore role.

check_role() tries to verify that the user has permission to become the
requested role, but this is inappropriate in a parallel worker, which
needs to exactly recreate the master's authorization settings.  So skip
the check in that case.

This fixes a bug in commit 924bcf4f16d54c55310b28f77686608684734f42.
