cld: common: Modify the vdev and offload peer conf
Modified the number of vdev as 3 from 4 as per the
new PRD and modified the number of offload peers
as (number of vdev + 1) and number reorder buffer as 4.
The current firmware implementation requires the number of offload peers
should be (number of vdevs + 1).
The reason for this is the firmware clubbed the self peer and offload peer
in the same pool. So if the firmware wanted to support n vdevs then the
number of offload peer must be n+1 of which n buffers will be used for
self peer and the remaining 1 is used for offload peer to support chatter
mode for single STA.
Technically the macro should be 1 however the current firmware
requires n+1.
TODO: This MACRO need to be modified in the future, if the firmware
modified to allocate buffers for self peer and offload peer
independently.
