USB: qc_rndis: Fix aggregation parameters settings issue
Currently driver does read max Transfer size from RNDIS_MSG_INIT
control message, when received from Host, but it is wrongly being
decoded due to wrong offset used. This leads dl_aggregation size set to
0 instead of required rndis_dl_aggr_size. Hence fix this by incrementing
tmp pointer for requestID to use correct offset to read max Transfer
size and set DL aggregation size correctly.
Also pass maxpkt_per_xfer as zero to rndis_qc_bind_config_vendor() so that
UL aggregation buffer size will be set to aggregation of 15 packets. This
helps in improving througput numbers.
