can: omit received RTR frames for single ID filter lists

Since commit d253eee20195b25e298bf162a6e72f14bf4803e5 the single CAN
identifier filter lists handle only non-RTR CAN frames.

So we need to omit the check of these filter lists when receiving RTR CAN frames.

Hello Dave & Greg,

while writing a CAN filter test suite on a business trip i discovered a 
missing check that became necessary together with the referenced commit

'can: Fix CAN_(EFF|RTR)_FLAG handling in can_filter'

Sorry for the effort of this extra patch.

It should go into 2.6.28 before the bug fix window closes.

Additionally the patch applies down to 2.6.26. Greg please consider this patch 
together with the referenced one for stable .26 and .27 also.

Thanks & best regards,
Oliver
