    audit: move the wait from the queue length from the commit to alloc

    AUDIT_SYSCALL_EXIT() and indirectly audit_commit() is intended to be
    called from arbitrary top-level context.  This means that any sleepable
    locks can be owned by the caller, and which makes the sleeping in
    audit_commit() forbidden.

    Since we need to sleep for the record in audit_alloc() anyway, move the
    sleep for the queue limit there.  At worst, if the audit is suspended is
    disabled when we actually reach the commit location, this means that we
    lost time uselessly.
