msm: ipa: enable SYSPIPE_ERR_DETECTION bit for deaggr_err

Browse source 
We observe the IPA RX stall due to the DEAGGR_ERR_IRQ
of PACKET_SIZE > FRAME_SIZE on rndis.
 In IPA, some of de-aggregation error handling checks
are dependent on the syspipe_err_detection config bit.
Adding IGNORE_MIN_PKT_ERR bit for rndis as well based
on recommendations.
