[PATCH] libsemanage: genhomedircon: only set MLS level if MLS is enabled

[Stephen Smalley <sds@tycho.nsa.gov>]

When a non-MLS policy was used with genhomedircon context_from_record()
in sepol would report an error because an MLS level was present when MLS
is disabled.  Based on a patch by Gary Tierney, amended to use
sepol_policydb_mls_enabled rather than semanage_mls_enabled because
we are testing the temporary working policy, not the active policy.
